Subject: [PATCH] drm/amd/pm: fix error code in smu_set_power_limit()
Date: Wed, 14 Apr 2021 08:59:22 +0300 [thread overview]
Message-ID: <YHaEutSVsa63kcFZ@mwanda> (raw)
We should return -EINVAL instead of success if the "limit" is too high.
Fixes: e098bc9612c2 ("drm/amd/pm: optimize the power related source code layout")
