Subject: [PATCH 0/2] ALSA: hda: Move component binding support into separate library

The Cirrus Logic amplifiers are currently paired with Realtek HDA codecs.
But they could be used with other codecs. To prepare for this, these two
patches move the manager side of the component binding out of the Realtek
driver into a library module.

The first patch tweaks the CS35L41 code so that it is not hardcoded to
CS35L41, and changes the TAS2781 handling so that it re-uses that code
instead of having a near-identical copy of it.

Can someone please test that these two patches don't break TAS2781?
I have checked that they should work in theory but I don't have hardware
to test on.
