In this patch, we put array_index_nospec() to the common snd_ctl_get_ioff*() helpers instead of each caller. These helpers are also referred from some drivers, too, and basically all usages are to calculate the array index from the user-space value, hence it's better to cover there.

The changes are scattered widely, and the majority of them are attributed to ASoC componentization. The gitk output made me dizzy, but it's slightly better than London tube. OK, below are some highlights: - Continued hardening works in ALSA PCM core; most of the existing syzkaller reports should have been covered. - USB-audio got the initial USB Audio Class 3 support, as well as UAC2 jack detection support and more DSD-device support. - ASoC componentization: finally each individual driver was converted to components framework, which is more future-proof for further works. Most of conversations were systematic. - Lots of fixes for Intel Baytrail / Cherrytrail devices with Realtek codecs, typically tablets and small PCs. - Fixes / cleanups for Samsung Odroid systems - Cleanups in Freescale SSI driver - New ASoC drivers: * AKM AK4458 and AK5558 codecs * A few AMD based machine drivers * Intel Kabylake machine drivers * Maxim MAX9759 codec * Motorola CPCAP codec * Socionext Uniphier SoCs * TI PCM1789 and TDA7419 codecs - Retirement of Blackfin drivers along with architecture removal" * tag 'sound-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (497 commits) ALSA: pcm: Fix UAF at PCM release via PCM timer access ALSA: usb-audio: silence a static checker warning ASoC: tscs42xx: Remove owner assignment from i2c_driver ASoC: mediatek: remove "simple-mfd" in the example ASoC: cpcap: replace codec to component ASoC: Intel: bytcr_rt5651: don't use codec anymore ASoC: amd: don't use codec anymore ALSA: usb-audio: fix memory leak on cval ALSA: pcm: Fix mutex unbalance in OSS emulation ioctls ASoC: topology: Fix kcontrol name string handling ALSA: aloop: Mark paused device as inactive ALSA: usb-audio: update clock valid control ALSA: usb-audio: UAC2 jack detection ALSA: pcm: Return -EBUSY for OSS ioctls changing busy streams ALSA: pcm: Avoid potential races between OSS ioctls and read/write ALSA: usb-audio: Integrate native DSD support for ITF-USB based DACs.

Not much change in the core but there s the transition of all the individual drivers over to components which is intended to support further core work. The goal is to make it easier to do further core work by removing the need to special case all the different driver classes in the core, many of the devices end up being used in multiple roles in modern systems. We also have quite a lot of new drivers added this month of all kinds, quite a few for simple devices but also some more advanced ones with more substantial code. - The biggest thing is the huge series from Morimoto-san which converted everything over to components. This is a huge change by code volume but was fairly mechanical - Many fixes for some of the Realtek based Baytrail systems covering both the CODECs and the CPUs, contributed by Hans de Goode. - Lots of cleanups for Samsung based Odroid systems from Sylwester Nawrocki. - The Freescale SSI driver also got a lot of cleanups from Nicolin Chen. - The Blackfin drivers have been removed as part of the removal of the architecture. - New drivers for AKM AK4458 and AK5558, several AMD based machines, several Intel based machines, Maxim MAX9759, Motorola CPCAP, Socionext Uniphier SoCs, and TI PCM1789 and TDA7419 2018-03-28T04:30:41+00:00 Dave Airlie airlied@redhat.com 2018-03-28T04:30:41+00:00 urn:sha1:2b4f44eec2be2688511c2b617d0e1b4f94c45ba4 Linux 4.16-rc7 This was requested by Daniel, and things were getting a bit hard to reconcile, most of the conflicts were trivial though. 2018-03-28T02:30:29+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:30:29+00:00 urn:sha1:8ee67bb80a61fef7e130acf8c7c74722d535fd80 2018-03-28T02:29:40+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:29:40+00:00 urn:sha1:165879a90b16b3e3a7ead59e5a082de01cd7af1a 2018-03-28T02:29:31+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:29:31+00:00 urn:sha1:e540808131a7e4ffd52acd44f493341881a5a176 2018-03-28T02:28:30+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:28:30+00:00 urn:sha1:cce67af3b85047c4c77de3183d08ddc92417a121 2018-03-28T02:26:30+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:26:30+00:00 urn:sha1:848272e9a38e78bf0c746774a93ed2ab0a5b7f13 2018-03-28T02:26:09+00:00 Mark Brown broonie@kernel.org 2018-03-28T02:26:09+00:00 urn:sha1:5b6d7104f65c6a9271da71db5be01d08c04584ea
