Subject: drm/i915: Make skl+ universal plane registers unlocked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 14ad15296d1fd067e54ad04d96056fe0aed61f2d
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Drop the locks around most universal plane register writes.
The lock isn't needed since each plane's register are neatly
contained on their own cachelines.
