Subject: drm: Add DRM_GEM_FOPS
Git-commit: 1981c35bf7533d70f295b184bbb638d280fe2f36
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
The DEFINE_DRM_GEM_FOPS() helper is a bit limiting if a driver wants to
provide additional file ops, like show_fdinfo().
v2: Split out DRM_GEM_FOPS instead of making DEFINE_DRM_GEM_FOPS
varardic
v3: nits
