[PATCH 0/5] ALSA: Allow NULL passed to snd_ctl_remove()

[Takashi Iwai <tiwai@suse.de>]

This is a small series of cleanup patches for the call patterns with
snd_ctl_remove() and NULL kcontrol.
Now snd_ctl_remove() accepts the NULL argument just like free() or
kfree(), so that the callers can be cleaned up without NULL checks.

No functional changes should be introduced by this patch set.
