[PATCH v4 0/3] Fixes to bridge/panel and ingenic-drm

Hi,

This is the V4 of my patchset that attempts to fix use-after-free errors
in bridge/panel.c and in the ingenic-drm driver.

Changes from v3:
- [1/3]: the code now checks (connector->dev) instead of
(!!panel_bridge->connector.dev)
- [2/3]: the macro is now called drmm_plain_encoder_alloc(), and moved
to <drm/drm_encoder.h>. It also takes funcs/name parameters to be more
similar to drmm_encoder_alloc(), although these parameters can very
well be NULL.
- [3/3] uses the new macro.

V3 had a 4th patch, which was already applied as it received a
reviewed-by tag and could be applied independently.

Cheers,
-Paul
