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.
