[media] cx25821-alsa: get rid of a __must_check warning The hole reason for __must_check is to not ignore an error. However, a "ret" value is used at cx25821 just to avoid the Kernel compilation to compain about it. That, however, produces another warning (with W=1): drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini': drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] With the current implementation of driver_for_each_device() and cx25821_alsa_exit_callback(), there's actually just one very unlikely condition where it will currently produce an error: if driver_find() returns NULL. Ok, there's not much that can be done, as it is on a driver's function that returns void, but it can at least print some message if the error happens.
