Subject: drm/rockchip: Fix an error handling path rockchip_dp_probe()
Git-commit: 5074376822fe99fa4ce344b851c5016d00c0444f
Patch-mainline: v6.0-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 jsc#PED-2849
Should component_add() fail, we should call analogix_dp_remove() in the
error handling path, as already done in the remove function.
Fixes: 152cce0006ab ("drm/bridge: analogix_dp: Split bind() into probe() and real bind()")
