dispatch_dirty_region was only returning -EINVAL error codes, otherwise it would return 0. The kernel returns -ENOSYS when the driver doesn't support damage tracking, so dispatch_dirty would never see the error and never disable damage tracking. Pass all errors back from dispatch_dirty_region and let dispatch_dirty deal with them. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com> |
