Subject[PATCH] ASoC: codecs: msm8916-wcd-analog: fix module autoload
Date
If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo snd_soc_msm8916_analog | grep alias
$

After this patch:

$ modinfo snd_soc_msm8916_analog | grep alias
alias: of:N*T*Cqcom,pm8916-wcd-analog-codecC*
alias: of:N*T*Cqcom,pm8916-wcd-analog-codec
