ASoC: Fixes for v3.16 A bigger batch of changes than I would like as I didn't send any for a few weeks without noticing how many had built up. They are almost all driver specific though, larger changes are: - Fixes to the newly added Baytrail/MAX98090 which look like some QA was missed on the microphone detection. - Deletion of some erroniously listed audio formats for Haswell. - Fix debugfs creation in the core so that we don't try to generate multiple directories with the same name, relatively large textually but simple to inspect by eye and test. - A couple of bugfixes for the rcar driver one of which which involves a bit of code motion to move initailisation of some hardware out of common paths into device specific ones. - Ensure both channels are powered up for mono outputs on Arizona devices, involving some simple data tables listing the outputs and a loop over them. - A couple of fixes to save and restore information on suspended and idle Samsung I2S controllers.
