Merge tag 'asoc-v4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v4.19 A fairly big update, including quite a bit of core activity this time around (which is good to see) along with a fairly large set of new drivers. - A new snd_pcm_stop_xrun() helper which is now used in several drivers. - Support for providing name prefixes to generic component nodes. - Quite a few fixes for DPCM as it gains a bit wider use and more robust testing. - Generalization of the DIO2125 support to a simple amplifier driver. - Accessory detection support for the audio graph card. - DT support for PXA AC'97 devices. - Quirks for a number of new x86 systems. - Support for AM Logic Meson, Everest ES7154, Intel systems with RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707.

+	 *    - The gadget hits memory before the descriptor write
+	 *      causing it to read an obsolete value.
+	 *
+	 * Thankfully the problem is limited to the USB gadget device, other
+	 * masters in the SoC all have a lower priority than the core, thus
+	 * ensuring that the store by the core arrives first.
