Recently snd-usb-audio driver received a new option, quirk_alias, to allow user to apply the existing quirk for a different device. This works for many quirks as is, but some still need more tune-ups: namely, some quirks check the USB vendor/device IDs in various places, thus it doesn't work as long as the ID is different from the expected one.
With this patch, the driver stores the aliased USB ID, so that these rest quirks per device ID are applied. The transition to use the cached USB ID was already done in the past, so what we needed now is only to overwrite chip->usb_id.
Sounds interesting. Would this work for snd_usb_interface_dsd_format_quirks() ?
Yes, as long as chip->usb_id is checked, this hack should take effect.
