Subject: linux-next: build warning after merge of the block tree

Hi Jens,

After merging the block tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

block/elevator.c: In function 'elv_iosched_store':
block/elevator.c:1102:2: warning: ignoring return value of 'strstrip', declared with attribute warn_unused_result [-Wunused-result]
  strstrip(elevator_name);
  ^

Introduced by commit

  d0f6e2da5871 ("block: Remove leading whitespace and trailing newline in elevator switch error message")

Cheers,
Stephen Rothwell
