From: Colin Ian King <colin.king(a)canonical.com> We need to include pcm_local.h to clean up some smatch warnings: symbol 'snd_pcm_timer_done' was not declared.

Also remove some extraneous tabs on empty lines and replace space intentation with a tab.

[alsa-devel] [alsa-lib] bug in USB-Audio.conf
by Alexander Tsoy 30 May '17

30 May '17

Hello! I've noticed that there is a bug in USB-Audio.conf. "USB- Audio.pcm.default" doesn't allow custom "default" definitions, but there is one: USB-Audio."Audiophile USB (tm)".pcm.default Moreover there is a typo in this definition in dsnoop args: DEVICE=1 -> DEV=1. So what is the best course of action here? We can fix USB- Audio.conf (I have a working patch that I've tested with another card) or given that Audiophile USB is likely already in a semi-broken state for a long time, may be it is better to remove the exclusion in the driver [1] and remove all definitions for this card from USB- Audio.conf? [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/ commit/?id=5ee20bc792467d7d612157e0a9962765aa943b08 -- Alexander Tsoy <alexander(a)tsoy.me>

[alsa-devel] [PATCH 00/15] make more driver use devm_of_platform_populate()
by Benjamin Gaignard 30 May '17

30 May '17

Number of calls to of_platform_populate() aren't unbalanced by a call to of_platform_depopulate() that could generate issue will loading/unloading the drivers. Make those drivers use devm_of_platform_populate() fix the problem without need to add remove function. In some case replacing of_platform_populate() by devm_of_platform_populate() allow to delete driver remove function and save some lines of code. This series of patches based on v4.12-rc3 tag.

[alsa-devel] [PATCH v2 0/3] ALSA: USB-descriptor endianness fixes
by Johan Hovold 30 May '17

30 May '17

These patches add missing endianness conversions when accessing the USB device-descriptor fields. In the process, clean up the us122l driver which had product-id conditionals sprinkled throughout. The final patch enables compile testing for us122l which currently depends on x86 but compiles just fine for arm. Note that these patches have only been compile tested. Johan v2 - enable compile testing rather than drop the us122l x86-dependency Johan Hovold (3): ALSA: usb-audio: fix Amanero Combo384 quirk on big-endian hosts ALSA: us122l: clean up US144 handling ALSA: us122l: enable compile testing sound/usb/Kconfig | 2 +- sound/usb/quirks.c | 2 +- sound/usb/usx2y/us122l.c | 36 ++++++++++++++++++------------------ sound/usb/usx2y/us122l.h | 2 ++ 4 files changed, 22 insertions(+), 20 deletions(-) -- 2.13.0
