soundwire: Fix acquiring bus lock twice during master release

2018-08-27T04:19:48+00:00

As part of sdw_stream_remove_master(), sdw_stream_remove_slave() is called
which results in bus lock being acquired twice.

So, fix it by performing specific Slave remove operations in
sdw_release_master_stream() instead of calling sdw_stream_remove_slave().

soundwire: Fix incorrect exit after configuring stream

2018-08-27T04:19:48+00:00

In sdw_stream_add_master() after the Master ports are configured,
the stream is released incorrectly.

So, fix it by avoiding stream release after configuring the Master
for the stream.
While at it, rename the label appropriately.

soundwire: Fix duplicate stream state assignment

2018-08-27T04:19:48+00:00

For a SoundWire stream it is expected that a Slave is added to the
stream before Master is added.

So, move the stream state to CONFIGURED after the first Slave is
added and remove the stream state assignment for Master add.
Along with these changes, add additional comments to explain the same.

soundwire: Respect all error codes from dev_pm_domain_attach()

2018-05-14T20:58:45+00:00

The limitation of being able to check only for -EPROBE_DEFER from
dev_pm_domain_attach() has been removed. Hence let's respect all error
codes and bail out accordingly.
