From: Takashi Iwai <tiwai@xxxxxxx> commit 22390ce786c59328ccd13c329959dee1e8757487 upstream. This is a fix equivalent with the upstream commit 22390ce786c5 ("ALSA: usb-audio: add Schiit Hel device to quirk table"), adapted to the earlier kernels up to 5.14.y. It adds the quirk entry with the old ignore_ctl_error flag to the usbmix_ctl_maps, instead. The original patch description says: The Shciit Hel device responds to the ctl message for the mic capture switch with a timeout of -EPIPE: usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1 usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1 usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1 usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1 This seems safe to ignore as the device works properly with the control message quirk, so add it to the quirk table so all is good.
