drm/rockchip: vop: Fix reset of state in duplicate state crtc funcs
[ Upstream commit13fc28804b
] struct rockchip_crtc_state members such as output_type, output_bpc and enable_afbc is always reset to zero in the atomic_duplicate_state crtc funcs. Fix this by using kmemdup on the subclass rockchip_crtc_state struct. Fixes:4e257d9eee
