Subject: [PATCH] drm/amd/powerplay: fix amd_powerplay_reset()
Date: Tue, 24 Oct 2017 12:44:18 +0300	[thread overview]
Message-ID: <20171024094418.za4qacxapyrud2m4@mwanda> (raw)

We accidentally inverted an if statement and turned amd_powerplay_reset()
into a no-op.

Fixes: ae97988fc89e ("drm/amd/powerplay: tidy up ret checks in amd_powerplay.c (v3)")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

IMHO, tidying unreadable double negatives is tricky and error prone but
still worth it in the long run.
