Takashi Iwai f056f2fef3 ALSA: Make control API taking controls_rwsem consistently
A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove()
 and snd_ctl_find_*() suppose the callers taking card->controls_rwsem.
 But it's error-prone and fragile.  This patch set tries to change
 those API functions to take the card->controls>rwsem internally by
 themselves, so that the drivers don't need to take care of lockings.
 
 After applying this patch set, only a couple of places still touch
 card->controls_rwsem (which are OK-ish as they need for traversing the
 control linked list).
