Hi, this is a fairly largish patchset to fix and clean up Intel LPE audio driver. Most of the patches are to clean up and refactoring of the codes. As you can see in the diffstat below, quite lots of codes (over 1600 lines) are reduced. Now the driver structure is flattened to a single layer, and it looks much like a normal driver. Besides the refactoring, there are a few major fixes: e.g. the fix for the PCM disconnection that confuses PA,. the fix for the possible sleep-in-atomic at hotplug, the fix for racy chmap accesses. As new features, the driver supports the runtime PM properly now, it sets the CA bit for DP, and it exposes the ELD via ALSA control element. The current code is available in topic/intel-lpe-audio-cleanup branch, and it's based on the DP-audio branch, topic/intel-lpe-audio-dp that I'm going to merge to for-next soon.
