Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6: (308 commits) ALSA: sound/pci/asihpi: check adapter index in hpi_ioctl ALSA: aloop - Fix possible IRQ lock inversion ALSA: sound/core: merge list_del()/list_add_tail() to list_move_tail() ALSA: ctxfi - use list_move() instead of list_del()/list_add() combination ALSA: firewire - msleep needs delay.h ALSA: firewire-lib, firewire-speakers: handle packet queueing errors ALSA: firewire-lib: allocate DMA buffer separately ALSA: firewire-lib: use no-info SYT for packets without SYT sample ALSA: add LaCie FireWire Speakers/Griffin FireWave Surround driver ALSA: hda - Remove an unused variable in patch_realtek.c ALSA: hda - pin-adc-mux-dmic auto-configuration of 92HD8X codecs ALSA: hda - fix digital mic selection in mixer on 92HD8X codecs ALSA: hda - Move default input-src selection to init part ALSA: hda - Initialize special cases for input src in init phase ALSA: ctxfi - Clear input settings before initialization ALSA: ctxfi - Fix SPDIF status retrieval ALSA: ctxfi - Fix incorrect SPDIF status bit mask ALSA: ctxfi - Fix microphone boost codes/comments ALSA: atiixp - Fix wrong time-out checks during ac-link reset ALSA: intel8x0m: append 'm' to "r_intel8x0" ...
