[PATCH 0/3] Fix some error handling paths in 'meson_drv_bind_master()'

[PATCH 0/3] Fix some error handling paths in 'meson_drv_bind_master()'

[Christophe JAILLET]

Patch 1 and 3 are fixes.
Patch 2 is just a kind of clean-up noticed while patching this driver.

If patch 2 is considered as useless, patch 3 can be applied on top of 
patch 1, it does nor depend on the 2nd patch.

Christophe JAILLET (3):
  drm/meson: Fix an un-handled error path in 'meson_drv_bind_master()'
  drm/meson: Use drm_dev_put() instead of drm_dev_unref()
  drm/meson: Fix some error handling paths in 'meson_drv_bind_master()'

[PATCH 2/3] drm/meson: Use drm_dev_put() instead of drm_dev_unref()

[Christophe JAILLET]

According to 'drivers/gpu/drm/drm_drv.c', 'drm_dev_unref()' is just a
compatibility alias for 'drm_dev_put()'. So use the latter instead.

[PATCH 3/3] drm/meson: Fix some error handling paths in 'meson_drv_bind_master()'

[Christophe JAILLET]

If one of these functions fail, we whould free 'drm', as alreadry done in
the other error handling paths, below and above.

Fixes: bbbe775ec5b5 ("drm: Add support for Amlogic Meson Graphic Controller")
