Merge tag 'drm-amdkfd-fixes-2015-02-02' of git://people.freedesktop.org/~gabbayo/linux into drm-fixes

Three small fixes that came up during last week, nothing scary:

- Accidently incremented a counter instead of decrementing it (copy-paste error)
- Module parameter of max num of queues must be at least 1 and not 0
- Don't do BUG() as a result from wrong user input

* tag 'drm-amdkfd-fixes-2015-02-02' of git://people.freedesktop.org/~gabbayo/linux:
  drm/amdkfd: Don't create BUG due to incorrect user parameter
  drm/amdkfd: max num of queues can't be 0
  drm/amdkfd: Fix bug in accounting of queues
