[PATCH linux-next] perf: remove unused variable

[Vincent Stehlé]

This fixes the following compilation warning:

  kernel/events/core.c: In function ‘perf_event_exit_task_context’:
  kernel/events/core.c:7434:35: warning: unused variable ‘tmp’ 
[-Wunused-variable]

Hi,

This can be seen with e.g. linux next-20140509 and arm allmodconfig.

Best regards,

V.
