[PATCH v2 09/12] drm/tilcdc: Handle drm_atomic_helper_swap_state failure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



drm_atomic_helper_swap_state() will be changed to interruptible waiting
in the next few commits, so all drivers have to be changed to handling
failure.
