[PATCH 03/43] ALSA: control: Allow to pass items zero to snd_ctl_enum_info()

[Takashi Iwai]

Although this is weird, some drivers want to allow empty control
elements intentionally, e.g. the number of items may change depending
on the firmware status. Let the function simply returning in such a
case.

This allows us to catch the bugs in drivers easily.

[Takashi Iwai]

Instead of the open code for the info call back of enum elements,
recommend the use of snd_ctl_elem_info(), which will reduce lots of
codes.
