Linux 3.11: Bay Trail Audio, 32+ Sound Cards

The sound/audio kernel driver pull request has been submitted for the Linux 3.11 merge window. The changes this time around aren't too exciting, but there's the continued bettering of the Linux audio stack.

Takashi Iwai notes in his pull request, "A relative calm release at this time with a flat diffstat. The only significant change in the ALSA core side is the support for more than 32 card instances, configurable via kconfig. Other than that, in both ASoC and other parts, mostly some improvements and fixes on the driver side."

Aside from being able to support more than 32 sound card instances, the Linux 3.11 audio changes include supporting Intel Bay Trail (the platform of next-generation Atom SoCs that also does the in-house "Valley View" graphics), ALC5505 DSP support in the HDA driver, new quirk handling, Yamaha/Roland USB audio device support, AC'97 refactoring bug-fixes, and various other clean-ups and new audio adapter device support.
