If the interface can't report a clock's validity, assume that it's valid. Signed-off-by: NDaniel Mack <zonque@gmail.com> Reported-by: NVicente Joel <vicentejoel@gmail.com> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

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.

It is not advisable to print a warning when a device does not support setting the sample rate because this is perfectly valid for devices with a single rate or where rates are implicitly changed by selecting another alternate setting.

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. Signed-off-by: NDaniel Mack <daniel@caiaq.de> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

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.

Audio devices which comply to the UAC2 standard can export complex clock topologies in its descriptors and set up links between them. The entities that are defined are - clock sources, which define the end-leafs. - clock selectors, which act as switch to select one out of many possible clocks sources. - clock multipliers, which have an input clock source, and act as clock source again. They can be used to derive one clock from another. All sample rate changes, clock validity queries and the like must go to clock source elements, while clock selectors and multipliers can be used as terminal clock source. The following patch adds a parser for these elements and functions to iterate over the tree and find the leaf nodes (clock sources). The samplerate set functions were moved to the new clock.c file.
