drm/rockchip: vop: Fix call to crtc reset helper

Browse source

[ Upstream commit 5aacd29083 ]

Allocation of crtc_state may fail in vop_crtc_reset, causing an invalid
pointer to be passed to __drm_atomic_helper_crtc_reset.

Fix this by adding a NULL check of crtc_state, similar to other drivers.

Fixes: 01e2eaf40c ("drm/rockchip: Convert to using __drm_atomic_helper_crtc_reset() for reset.")
