sound fixes for 4.14-rc6 We've got slightly more fixes than wished, but heading to a good shape. Most of changes are about HD-audio fixes, one for a buggy code that went into 4.13, and another for avoiding a crash due to buggy BIOS. Apart from HD-audio, a sequencer core change that is only for UP config (which must be pretty rare nowadays), and a USB-audio quirk as usual.
