[alsa-devel] [PATCH 2/5] ALSA: snd_usb_caiaq: give better shortname

[Daniel Mack]

Give the card an 'id' name which will prevent ALSA from calling
choose_default_name(). This implementation only took the last part of a
name containing whitespaces which for example caused 'Audio 4 DJ' to be
shortened to 'DJ', which was not very descriptive.

The implementation now takes the short name and removes all whitespaces
from it which is much nicer.
