Pull sound fixes from Takashi Iwai: "No big surprises here, just a few device-specific fixes. HD-audio received several fixes for Acer, Dell, Huawei and other laptops as well as the workaround for the new Intel chipset. One significant one-liner fix is the disablement of the node-power saving on Realtek codecs, which may potentially cover annoying bugs like the background noises or click noises on many devices. Other than that, a fix for FireWire bit definitions, and another fix for LINE6 USB audio bug that was discovered by syzkaller" * tag 'sound-5.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: fireface: Use ULL suffixes for 64-bit constants ALSA: hda/realtek - Improve the headset mic for Acer Aspire laptops ALSA: line6: Assure canceling delayed work at disconnection ALSA: hda - Force polling mode on CNL for fixing codec communication ALSA: hda/realtek - Enable micmute LED for Huawei laptops ALSA: hda/realtek - Set default power save node to 0 ALSA: hda/realtek - Check headset type by unplug and resume
