Subject: drm/bridge: anx7625: Convert to use devm_kzalloc
Git-commit: 57bfb34a51c7c655335010b3168c1061b5eba354
Patch-mainline: v5.18-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 devm_kzalloc instead of kzalloc and drop kfree(). Let the memory
handled by driver detach.
