From b6a83d928c652c092acd1ce79c19d44a1da9a6db Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@oracle.com> Date: Mon, 7 Apr 2014 15:39:03 -0700 Subject: [PATCH] drivers/misc/sgi-gru/grukdump.c: cleanup gru_dump_context() a little "ret" is zero here so we can remove the "!ret" part of the condition. "uhdr" is alread a __user pointer so we can remove the cast.
