Subject: drm/gma500: Fix wrong pointer passed to PTR_ERR()
Git-commit: ebe180d376a5f7b2e534b69d237aa6fab43008ee
Patch-mainline: v5.16-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
PTR_ERR() should access the value just tested by IS_ERR(),
otherwise the wrong error code will be returned.
