This patch adds a new option "quirk_alias" to snd-usb-audio driver for allowing user to pass the quirk alias list. A quirk alias consists of a string form like 0123abcd:5678beef, which makes to apply a quirk to a device with USB ID 0123:abcd treated as if it were 5678:beef. This feature is useful to test an existing quirk, typically for a newer model of the same vendor, without patching / rebuilding the kernel driver. The current implementation is fairly simplistic: since there is no API for matching a usb_device_id to the given ID pair, it has an open code to loop over the id table and matches only with vendor:product pair. So far, this is OK, as all existing entries are with vendor:product pairs, indeed. Once when we have another matching entry, however, we'd need to update get_alias_quirk() as well. Note that this option is provided only for testing / development. If you want to have a proper support, contact to upstream for adding the matching quirk in the driver code statically.
