[PATCH -next] drm/amd/display: Delete redundant null check for 'steam' and 'plane'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since commit 15c2990e0f01 ("drm/amd/display: Add null checks for
'stream' and 'plane' before dereferencing"), the
dcn30_apply_idle_power_optimizations() function would return
if these veriables would be null. So no need to check again before
using them.
