[alsa-devel] [PATCH RFC 0/3] Add USB-audio quirk alias option

[Takashi Iwai]

Hi,

this is an experimental patchset to add a new option, quirk_alias, to
snd-usb-audio driver.  It allows to use the existing quirk for the
given vendor:product id pair matching with the new device.  Passing
like:
  quirk_alias=1234abcd:5678beef
will make the driver applying the quirk for 5678:beef against to the
new device 1234:abcd.

Obviously, this is for helping to find a workaround for a new device
that may need the same / similar quirk for the previous models.  Then
you can apply the quirk without recompiling the kernel driver with a
manual patch.
