Subject: [PATCH] [ALSA] usb/caiaq: decrease period_bytes_min
This patch decreases the snd_pcm_hardware->period_bytes_min field in the
caiaq/usb audio driver. The hardware can actually handle as few as 128
bytes, depending on the system. So it makes no sense to keep
applications from actually using such values.
