Subject: [PATCH] ASoC: codecs: wcd938x: remove incorrect module interdependency
For some reason we ended up with cyclic dependency between snd_soc_wcd938x
and snd_soc_wcd938x_sdw modules.
Remove this cyclic dependency by handling them in respective modules.
Without this below error is reported during make modules_install
depmod: ERROR: Cycle detected: snd_soc_wcd938x -> snd_soc_wcd938x_sdw -> snd_soc_wcd938x
depmod: ERROR: Found 2 modules in dependency cycles!
Fixes: 045442228868 ("ASoC: codecs: wcd938x: add audio routing and Kconfig")
Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>
