Skipped "ALSA: hda: cs35l41: Support systems with missing _DSD 
properties" because you already submitted that for 
https://bugs.launchpad.net/bugs/2039151 (btw there also with "ALSA: hda: 
cs35l41: Fix the loop check in cs35l41_add_dsd_properties" which is a 
fixup for the patch which now was skipped.

This really does not instill a lot of trust in those bulk submissions... 
Anyhow now

Applied to mantic:linux/master-next. Thanks.
