[Intel-gfx] [PATCH 0/3] drm: drm_sysfs_connector_add() stuff

[ville.syrjala at linux.intel.com]

Most drivers don't appear to bother with checking drm_connector_sysfs_add()
return value. That means the recent changes to drm_connector_sysfs_add()
have left most drivers susceptible to oopsing on cleanup if
drm_connector_sysfs_add() somehow failed.

This series makes drm_connector_sysfs_remove() safe to call even if
drm_connector_sysfs_add() failed. I also went a bit further and changed
i915 to check the drm_connector_sysfs_add() return value. Not sure if we
really want that patch now that the danger of oopsing is eliminated...

Ville Syrjälä (3):
      drm/sysfs: Remove stale comments about calling drm_sysfs_connector_add() multiple times
      drm/sysfs: Don't pollute connector->kdev if drm_connector_sysfs_add() fails
      drm/i915: Clean up if drm_sysfs_connector_add() fails
