Hi,

this is a series of patches to just convert the plain info callback for enum ctl elements to snd_ctl_elem_info(). Also, it includes the extension of snd_ctl_elem_info(), for catching the unexpected string cut-off and handling the zero items.

New subject: [alsa-devel] [PATCH 01/43] ALSA: doc: Recommend the use of snd_ctl_elem_info()

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.

New subject: [alsa-devel] [PATCH 03/43] ALSA: control: Allow to pass items zero to snd_ctl_enum_info()

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.
