       "No surprises in this development cycle, and most of work is about the
        fixes and the improvements of the existing code, while a new LED
        control layer and a few new drivers have been introduced.
        Here are some highlights:
         - A common mute-LED framework was introduced. It is used by HD-audio
           for now, more adaption will follow later. The former "Mic Mute-LED
           Mode" mixer control has been replaced with the corresponding sysfs
         - User-control management was changed to count consumed bytes instead
           of capping by number of elements; this will allow more controls in
           the normal usage pattern while avoiding the possible memory
           exhaustion DoS
         - Continued refactoring and cleanups in ASoC core and generic card
         - Wide range of small cppcheck and warning fixes
         - New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
           accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
         - Continued improvements and fixes of the implicit feedback mode,
           including better support for Pioneer and Roland/BOSS devices
         - Default back to non-buffer preallocation on x86
         - Cirrus codec improvements, more quirks for Realtek codecs
         - New virtio sound driver
         - FireWire Bebob updates"

      Pull module updates from Jessica Yu:
       "Fix an age old bug involving jump_calls and static_labels when
        When CONFIG_MODULE_UNLOAD=n, it means you can't unload modules, so
        normally the __exit sections of a module are not loaded at all.
        However, dynamic code patching (jump_label, static_call, alternatives)
        can have sites in __exit sections even if __exit is never executed.
        Reported by Peter Zijlstra:
           'Alternatives, jump_labels and static_call all can have relocations
            into __exit code. Not loading it at all would be BAD.'
        Therefore, load the __exit sections even when CONFIG_MODULE_UNLOAD=n,
        and discard them after init"

      drm/tegra: Changes for v5.13-rc1
      The changes this time around contain a couple of fixes for host1x along
      with some improvements for Tegra DRM. Most notably the Tegra DRM driver
      now supports the hardware cursor on Tegra186 and later, more correctly
      reflects the capabilities of the display pipelines on various Tegra SoC
      generations and knows how to deal with the dGPU sector layout by using
      framebuffer modifiers.

      Pull xfs updates from Darrick Wong:
       "The notable user-visible addition this cycle is ability to remove
        space from the last AG in a filesystem. This is the first of many
        changes needed for full-fledged support for shrinking a filesystem.
        Still needed are (a) the ability to reorganize files and metadata away
        from the end of the fs; (b) the ability to remove entire allocation
        groups; (c) shrink support for realtime volumes; and (d) thorough
        testing of (a-c).
        There are a number of performance improvements in this code drop: Dave
        streamlined various parts of the buffer logging code and reduced the
        cost of various debugging checks, and added the ability to pre-create
        the xattr structures while creating files. Brian eliminated
        transaction reservations that were being held across writeback (thus
        reducing livelock potential.
        Other random pieces: Pavel fixed the repetitve warnings about
        deprecated mount options, I fixed online fsck to behave itself when a
        readonly remount comes in during scrub, and refactored various other
        parts of that code, Christoph contributed a lot of refactoring this
        cycle. The xfs_icdinode structure has been absorbed into the (incore)
        xfs_inode structure, and the format and flags handling around
        xfs_inode_fork structures has been simplified. Chandan provided a
        number of fixes for extent count overflow related problems that have
        been shaken out by debugging knobs added during 5.12.
         - Various minor fixes in online scrub.
         - Prevent metadata files from being automatically inactivated.
         - Validate btree heights by the computed per-btree limits.
         - Don't warn about remounting with deprecated mount options.
         - Initialize attr forks at create time if we suspect we're going to
           need to store them.
         - Reduce memory reallocation workouts in the logging code.
         - Fix some theoretical math calculation errors in logged buffers that
           span multiple discontig memory ranges but contiguous ondisk
         - Speedups in dirty buffer bitmap handling.
         - Make type verifier functions more inline-happy to reduce overhead.
         - Reduce debug overhead in directory checking code.
         - Many many typo fixes.
         - Begin to handle the permanent loss of the very end of a filesystem.
         - Fold struct xfs_icdinode into xfs_inode.
         - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
         - Remove a broken directory block format check from online scrub.
         - Fix a bug where we could produce an unnecessarily tall data fork
           btree when creating an attr fork.
         - Fix scrub and readonly remounts racing.
         - Fix a writeback ioend log deadlock problem by dropping the behavior
           where we could preallocate a setfilesize transaction.
         - Fix some bugs in the new extent count checking code.
         - Fix some bugs in the attr fork preallocation code.

      Pull clk updates from Stephen Boyd:
       "Here's a collection of largely clk driver updates. The usual suspects
        are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
        but it feels pretty light on commits.
        There's only one real commit to the framework core and that's to
        consolidate code. Otherwise the diffstat is dominated by many Qualcomm
        clk driver patches that modernize the driver for the proper way of
        speciying clk parents. That's shifting data around, which could subtly
        break things so I'll be on the lookout for fixes.
        New Drivers:
         - Proper clk driver for Mediatek MT7621 SoCs
         - Support for the clock controller on the new Rockchip rk3568
         - Simplify Zynq Kconfig dependencies
         - Use clk_hw pointers in socfpga driver
         - Cleanup parent data in qcom clk drivers
         - Some cleanups for rk3399 modularization
         - Fix reparenting of i.MX UART clocks by initializing only the ones
           associated to stdout
         - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
         - Make i.MX LPCG and SCU clocks return on registering failure
         - Kernel doc fixes
         - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
         - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
         - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on
           Renesas R-Car V3U

      Pull io_uring updates from Jens Axboe:
       - Support for multi-shot mode for POLL requests
       - More efficient reference counting. This is shamelessly stolen from
         the mm side. Even though referencing is mostly single/dual user, the
         128 count was retained to keep the code the same. Maybe this
         should/could be made generic at some point.
       - Removal of the need to have a manager thread for each ring. The
         manager threads only job was checking and creating new io-threads as
         needed, instead we handle this from the queue path.
       - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
         thread is "just" a regular application thread, so no need to restrict
         use of it anymore.
       - Cleanup of how internal async poll data lifetime is managed.
       - Fix for syzbot reported crash on SQPOLL cancelation.
       - Make buffer registration more like file registrations, which includes
         flexibility in avoiding full set unregistration and re-registration.
       - Fix for io-wq affinity setting.
       - Be a bit more defensive in task->pf_io_worker setup.
       - Various SQPOLL fixes.
       - Cleanup of SQPOLL creds handling.
       - Improvements to in-flight request tracking.
       - File registration cleanups.
       - Tons of cleanups and little fixes

      net: dsa: ksz: Make reg_mib_cnt a u8 as it never exceeds 255 · 12c2bb96
      Colin Ian King authored
      Currently the for-loop in ksz8_port_init_cnt is causing a static
      analysis infinite loop warning with the comparison of
      mib->cnt_ptr < dev->reg_mib_cnt. This occurs because mib->cnt_ptr
      is a u8 and dev->reg_mib_cnt is an int and the analyzer determines
      that mib->cnt_ptr potentially can wrap around to zero if the value
      in dev->reg_mib_cnt is > 255. However, this value is never this
      large, it is always less than 256 so make reg_mib_cnt a u8.
