Just some minor tidy ups and preparation for starting to upstream some Cirrus SoundWire devices. The first three patches are pretty trivial, the last patch which moves the remaining core over to using the no_pm functions could probably use some careful review.

Changes since v2: - Fix up a memory leak of a buffer on the error path - Added some reviewed by's

Thanks, Charles

Charles Keepax (3): soundwire: Provide build stubs for common functions soundwire: debugfs: Switch to sdw_read_no_pm soundwire: stream: Move remaining register accesses over to no_pm

Simon Trimmer (1): soundwire: bus: export sdw_nwrite_no_pm and sdw_nread_no_pm functions
