[PATCH 17/21] drm/tilcdc: remove check for return value of debugfs functions.

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

 



Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files() never
fails. Therefore, remove the check and error handling of the return
value of drm_debugfs_create_files() as it is not needed in
tilcdc_debugfs_init().

Also remove local variables that are not used after the changes, and
declare tilcdc_debugfs_init() as void.
