Subject: drm/msm/dp: remove extra wrappers and public functions
Git-commit: 13ea4799a81b48aca810e1639d7bbeb2792709ac
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
dp_bridge's functions are thin wrappers around the msm_dp_display_*
family. Squash dp_bridge callbacks into respective msm_dp_display
functions, removing the latter functions from public space.
