[alsa-devel] [PATCH v5 07/17] soundwire: slave: move uevent handling to slave device level

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

Currently the .uevent callback is set at the bus level. This is not
necessary, we only really need to deal with uevents for the Slave
device, so move the uevent handling at that level.
