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 v1: - patch [1/3]: the connector is cleaned up only if it was initialized in the first place; - patch [2/3]: use __drmm_simple_encoder_alloc; - patch [3/3] 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.
