sound fixes for 3.11-rc2
Except for a slightly big OMAP changes, all rest are small, mostly boring changes; all either 3.11 regression fixes or stable materials. - ASoC OMAP fixes due to non-DT OMAP4 removals - Other ASoC driver changes (sglt5000, wm8978, wm8948, samsung) - Fix missing locking for snd_pcm_stop() calls in many drivers - Fix the blocking request_module() in OSS sequencer - Fix old OSS vwsnd driver builds - Add a new HD-audio HDMI codec ID -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAABAgAGBQJR5/PFAAoJEGwxgFQ9KSmkqb0QAJ9pio0iRL2T+N8m4deTAn/E 71suhNyMmqEwSt86UtOO6N/QKGCsUhQA1tXCWKgLE9Dqo4f3S7fWD0cGKDdk53QZ D3qwjTPvFP05gMSmAkKxPr8C48HTrngSUxdrV5BSU0goRXYa/qqP7H1+jRbIhNv+ 1WBXQJ8I0ALqLqs2MCw22snCVp6SOnYzvBn543jcJOf+weDqZ/tWlfgzhZAlIvKJ OSkL8t+hiEyadjW/jSKm8Xe2Onb7tqZFG/x9ZggLq5HWQm7q261f3785X6EBtAKR nm8yZZW88JGrVvCRwuE1hJNSptnIhFFYTc+DeQiicYMKT5ixgSG3N99sMYQcsi5J jSUhLHeg3KeT44s//B+Vd/++lrwz5wcvnCLrcl0LqFaVrdIaZo6UUTMUHFPnl74f mIqpGgQBH7dcbYUWF4X26Y2qpvbZmNaHmd++0ywVNz7ponue1DKtaGfeiYEFyzDw BTnLI+sqg/1Y85ydE/04izeNtcS3y+iUw6A8slB+eS6MGl3B05oVZSewJOJhMccy +pn0Y/BvPNf/IxcHgRQ65GZmbGTW3sWv1syPqYvXRHeiYYv9Ekf55Nr+LKPpFJdj M9G4BBo56Y+xC8UpHYgcGfzmW8P+rzpc+yuGZC/z6kFO0Y9LL9ABUMOHhk4mPD7d 5/GebLUeG8gowWV8zgVP =xUZh -----END PGP SIGNATURE----- Merge tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "Except for a slightly big OMAP changes, all rest are small, mostly boring changes; all either 3.11 regression fixes or stable materials. - ASoC OMAP fixes due to non-DT OMAP4 removals - Other ASoC driver changes (sglt5000, wm8978, wm8948, samsung) - Fix missing locking for snd_pcm_stop() calls in many drivers - Fix the blocking request_module() in OSS sequencer - Fix old OSS vwsnd driver builds - Add a new HD-audio HDMI codec ID" * tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (23 commits) ALSA: seq-oss: Initialize MIDI clients asynchronously ALSA: hda - Add new GPU codec ID to snd-hda staging: line6: Fix unlocked snd_pcm_stop() call [media] saa7134: Fix unlocked snd_pcm_stop() call ASoC: s6000: Fix unlocked snd_pcm_stop() call ASoC: atmel: Fix unlocked snd_pcm_stop() call ALSA: pxa2xx: Fix unlocked snd_pcm_stop() call ALSA: usx2y: Fix unlocked snd_pcm_stop() call ALSA: ua101: Fix unlocked snd_pcm_stop() call ALSA: 6fire: Fix unlocked snd_pcm_stop() call ALSA: atiixp: Fix unlocked snd_pcm_stop() call ALSA: asihpi: Fix unlocked snd_pcm_stop() call sound: oss/vwsnd: Always define vwsnd_mutex sound: oss/vwsnd: Add missing inclusion of linux/delay.h ASoC: wm8978: enable symmetric rates ASoC: omap-mcbsp: Use different method for DMA request when booted with DT ASoC: omap-dmic: Do not use platform_get_resource_byname() for DMA ASoC: omap-mcpdm: Do not use platform_get_resource_byname() for DMA ASoC: omap-pcm: Request the DMA channel differently when DT is involved ASoC: Samsung: Set RFS and BFS in slave mode ...
