From 896c59edcdafc4e213761184294cbccf47126a23 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 23 Nov 2022 16:54:26 +0000 Subject: [PATCH] ASoC: rt1308-sdw: Switch to new snd_sdw_params_to_config helper The conversion from hw_params to SoundWire config is pretty standard as such most of the conversion can be handled by the new snd_sdw_params_to_config helper function.
