Subject: [PATCH 1/2] drm/amd/display: Fix incorrect power gating configuration for DOMAIN10
The current implementation incorrectly updates DOMAIN10_PG_CONFIG with
DOMAIN8_POWER_FORCEON, which is not the intended behavior. This patch
corrects the power gating configuration by updating DOMAIN10_PG_CONFIG
with DOMAIN10_POWER_FORCEON, preventing potential issues related to
power management.
Fixes: 46825fcfbe16 ("drm/amd/display: avoid power gate domains that doesn't exist")
