[PATCH 4.4 080/163] drm/amdkfd: uninitialized variable in dbgdev_wave_control_set_registers()

From: Greg Kroah-Hartman
Date: Mon May 02 2016 - 21:42:22 EST

4.4-stable review patch. If anyone has any objections, please let me know.


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 93fce954427effee89e44a976299b15dd75b4bbc upstream.

At the end of the function we expect "status" to be zero, but it's
either -EINVAL or uninitialized.

Fixes: 788bf83db301 ('drm/amdkfd: Add wave control operation to debugger')
