git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There have been some significant changes in the core side, both for ALSA and ASoC, while lots of development have been seen in SOF, as well as many small fixes/improvements for ASoC codecs and platforms. Below is a highlight in this cycle: Core: - The unification of PCM vmalloc buffer allocation helpers into the standard API - Clean up of the default PCM mmap handling for vmalloc & SG-buffer - Fix potential races at ALSA timer open - A few new PCM API extensions; just preliminary core changes, the actual changes in drivers will be merged in 5.6 - Continued ASoC componentization works; now almost everything is a common ASoC component object. A lot of refactoring and simplification have been done along with it. ASoC: - Many fixes to the Sound Open Firmware (SOF) code - Wake on voice support for Chromebooks - SPI support and trigger word detection for RT5677 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770 HD-audio: - Improved Intel DSP configuration / probe code for SOF - Plumbing the legacy HD-audio driver with Intel SOF HDMI - DP-MST support for Nvidia HDMI codecs - Realtek quirks cleanups and new additions as usual Others: - Lots of refactoring and cleanups for FireWire; period-size sharing, h/w IRQ interval configuration, clock recovery improvements, etc - USB-audio: Scarlett mixer quirks - Cleanups of PCM calls in various drivers (including media and USB) to adapt the core API changes" * tag 'sound-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (497 commits) ALSA: usb-audio: Fix Focusrite Scarlett 6i6 gen1 - input handling ALSA: hda/realtek - Enable internal speaker of ASUS UX431FLC ALSA: aloop: Fix dependency on timer API ASoC: DMI long name - avoid to add board name if matches with product name ASoC: improve the DMI long card code in asoc-core ASoC: rsnd: fix DALIGN register for SSIU ALSA: aloop: Avoid unexpected timer event callback tasklets ALSA: aloop: Remove redundant locking in timer open function ASoC: component: Add sync_stop PCM ops ASoC: pcm: Make ioctl ops optional ALSA: hda/hdmi - Clear codec->relaxed_resume flag at unbinding ALSA: hda - Disable audio component for legacy Nvidia HDMI codecs ALSA: cs4236: fix error return comparison of an unsigned integer ALSA: usb-audio: Fix NULL dereference at parsing BADD ALSA: usb-audio: Fix Scarlett 6i6 Gen 2 port data ALSA: hda/realtek - Enable the headset-mic on a Xiaomi's laptop ALSA: hda/realtek - Move some alc236 pintbls to fallback table ALSA: hda/realtek - Move some alc256 pintbls to fallback table ALSA: docs: Update about the new PCM sync_stop ops ALSA: pcm: Add card sync_irq field ...

SYM_END(name, sym_type) SYM_FUNC_START(name) SYM_FUNC_END(name) SYM_CODE_START(name) SYM_CODE_END(name) SYM_DATA_START(name) SYM_DATA_END(name) etc - with about three times of these basic primitives with some label, local symbol or attribute variant, expressed via postfixes.

2019-11-23net: phy: remove phy_ethtool_sset()Russell King
There are no users of phy_ethtool_sset() in the kernel anymore, and as of commit 3c1bcc8614db ("net: ethernet: Convert phydev advertize and supported from u32 to link mode"), the implementation is slightly buggy - it doesn't correctly check the masked advertising mask as it used to. Remove it, and update the phy documentation to refer to its replacement function.

2019-11-21block: add iostat counters for flush requestsKonstantin Khlebnikov
Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.
