[PATCH 0/2] A couple hist trigger fixes

[Tom Zanussi <tom.zanussi@linux.intel.com>]

These are a couple of small fixes for problems pointed out by Dan
Carpenter.

patch 1, pointed out by Smatch though not actually a bug, cleans up
the code to explicitly check for something that was implied.  Thanks
to Steve Rostedt for suggesting the fix.

patch 2 fixes a PTR_ERR problem similar to the one previously
reported by Dan.

The following changes since commit d50c744ecde7ee3ba4d7ffb0e1c55e7a2f6bbc8e:

  tracing: Fix unsigned comparison to zero in hist trigger code (2016-04-19 18:56:05 -0400)
