Subject: [PATCH] drm/nouveau/therm: remove redundant duty == target check
Date: Tue, 19 Dec 2023 15:03:18 +0000 [thread overview]
Message-ID: <20231219150318.368398-1-colin.i.king@gmail.com> (raw)
The check for duty == target is always false because it is in an if block
where duty != target. A previous change added the duty != target check
and so the check duty == target check is now redundant and can be removed.
Cleans up a cppcheck warning:
drivers/gpu/drm/nouveau/nvkm/subdev/therm/fan.c:93:17: warning: Opposite
inner 'if' condition leads to a dead code block. [oppositeInnerCondition]
Fixes: e4311ee51d1e ("drm/nouveau/therm: remove ineffective workarounds for alarm bugs")
