Drop inbound packets that are smaller than expected. This has been
observed at the very beginning of the streaming transaction.

And when the hardware is in panic mode (which can only very rarely
happen in case of massive EMI chaos), mute the input channels.

Limit the number of printed warnings to one in case of streaming errors.
printk() happens to be expensive, especially in code called as often as
here.

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.

Fix section mismatch in caiaq: these __devinit functions can be

This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.
