From 9431f8df233f808baa5fcc62b520cc6503fdf022 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 13 Jul 2021 15:04:17 +0100 Subject: ASoC: codecs: wcd938x: make sdw dependency explicit in Kconfig currenlty wcd938x has only soundwire interface and depends on symbols from wcd938x soundwire module, so make this dependency explicit in Kconfig Without this one of the randconfig endup setting CONFIG_SND_SOC_WCD938X=y CONFIG_SND_SOC_WCD938X_SDW=m resulting in some undefined reference to wcd938x_sdw* symbols.
