Subject: drm/bridge: lt9611: Switch to atomic operations
Git-commit: 97d7ca798a79a93b2a3168f60024fddcc8e0d6b0
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
Use the atomic version of the enable/disable operations to continue the
transition to the atomic API. This will be needed to access the mode
from the atomic state.
