ALSA: usb-audio: include format.h in format.c

Just in case a prototype changes, we'll be warned. This also fixes a
sparse warning.

ALSA: usb-audio: fix detection of vendor-specific device protocol settings

2010-09-03T20:36:39+00:00

The Audio Class v2 support code in 2.6.35 added checks for the
bInterfaceProtocol field.  However, there are devices (usually those
detected by vendor-specific quirks) that do not have one of the
predefined values in this field, which made the driver reject them.

To fix this regression, restore the old behaviour, i.e., assume that
a device with an unknown bInterfaceProtocol field (other than
UAC_VERSION_2) has more or less UAC-v1-compatible descriptors.

ALSA: sound/usb/format: silence uninitialized variable warnings

2010-08-15T12:28:20+00:00

Gcc complains that ret might be used uninitialized:

sound/usb/format.c: In function ‘snd_usb_parse_audio_format’:
sound/usb/format.c:354: warning: ‘ret’ may be used uninitialized in this function
sound/usb/format.c:354: note: ‘ret’ was declared here
sound/usb/format.c:414: warning: ‘ret’ may be used uninitialized in this function
sound/usb/format.c:414: note: ‘ret’ was declared here

I suppose it could be uninitialized if there is ever a UAC_VERSION_3
released. Anyway this patch is worthwhile if only to silence the gcc
warning.

ALSA: usb-audio: simplify control interface access

2010-06-23T14:10:23+00:00

As the control interface is now carried in struct snd_usb_audio, we can
simplify the API a little and also drop the private ctrlif field from
struct usb_mixer_interface.

Also remove a left-over function prototype in pcm.h.

ALSA: usb-audio: parse UAC2 sample rate ranges correctly

2010-06-11T16:06:12+00:00

A device may report its supported sample rates in ranges rather than in
discrete triplets. The code used to only parse the MIN field instead of
properly paying attention to the MAX and RES values.

Also, handle RES values of 1 correctly and announce a continous sample
rate range in this case.

ALSA: usb-audio: fix control messages for USB_RECIP_INTERFACE

2010-06-11T16:05:38+00:00

Control messages directed to an interface must have the interface number
set in the lower 8 bits of wIndex. This wasn't done correctly for some
clock and mixer messages.
