From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>
None of the existing codec drivers set the sdw_driver.name, but
instead set sdw_driver.driver.name.
This leads to error messages such as
[ 23.935355] rt700 sdw:2:25d:700:0: Probe of (null) failed: -19
We could remove this sdw_driver.name if it doesn't have any
purpose. This patch only suggests using the proper indirection.
