drm/rockchip: Fix an error handling path rockchip_dp_probe()

2022-08-17T12:40:58Z

[ Upstream commit 5074376822fe99fa4ce344b851c5016d00c0444f ] Should component_add() fail, we should call analogix_dp_remove() in the error handling path, as already done in the remove function.

drm/rockchip: vop: Don't crash for invalid duplicate_state()

2022-08-17T12:40:58Z

[ Upstream commit 1449110b0dade8b638d2c17ab7c5b0ff696bfccb ] It's possible for users to try to duplicate the CRTC state even when the state doesn't exist. drm_atomic_helper_crtc_duplicate_state() (and other users of __drm_atomic_helper_crtc_duplicate_state()) already guard this with a WARN_ON() instead of crashing, so let's do that here too.

drm/rockchip: vop: fix possible null-ptr-deref in vop_bind()

2022-06-09T08:30:05Z

[ Upstream commit f8c242908ad15bbd604d3bcb54961b7d454c43f8 ] It will cause null-ptr-deref in resource_size(), if platform_get_resource() returns NULL, move calling resource_size() after devm_ioremap_resource() that will check 'res' to avoid null-ptr-deref.
