Subject: drm/bridge: tc358767: don't warn if display side ASSR enable fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87291e5dbae94da1ddd3966272e0d7d6dc7232f1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/bridge: tc358767: don't warn if display side ASSR enable fails

ASSR is an optional feature, so it's a valid operating condition for
the display to reject ASSR enable. Demote the warning to the debug
level.
