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@canb.auug.org.au Signed-off-by: Srinivas Kandagatla srinivas.kandagatla@linaro.org --- Changes since v1: - included irq.h as x86 allmodconfig build reported implicit declaration of function handle_nested_irq
