[PATCH v3 0/4] Fixes to bridge/panel and ingenic-drm

Hi,

Here are three independent fixes. The first one addresses a
use-after-free in bridge/panel.c; the second one addresses a
use-after-free in the ingenic-drm driver; finally, the third one makes
the ingenic-drm driver work again on older Ingenic SoCs.

Changes from v2:
- patch [1/4] added a FIXME.
- patch [2/4] is new. It introduces a drmm_plain_simple_encoder_alloc()
  macro that will be used in patch [3/4].
- patch [3/4] uses the macro introduced in patch [2/4].
- patch [4/4] is unmodified.

Note to linux-stable guys: patch [v2 2/3] will only apply on the current
drm-misc-next branch, to fix it for v5.11 and older kernels, use the V1
of that patch.

Cheers,
-Paul
