[PATCH v2 0/8] drm: writeback: clean up writeback connector initialization

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

Drivers using drm_writeback_connector_init() / _with_encoder() don't
perform cleanup in a manner similar to drmm_writeback_connector_init()
(see drm_writeback_connector_cleanup()). Migrate all existing drivers
to use drmm_writeback_connector_init(), drop
drm_writeback_connector_init() and drm_writeback_connector::encoder
(it's unused afterwards).

This series leaves former drm_writeback_connector_init_with_encoder()
(renamed to drm_writeback_connector_init as a non-managed counterpart
for drmm_writeback_connector_init()). It is supposed to be used by
drivers which can not use drmm functions (like Intel). However I think
it would be better to drop it completely.
