Subject: [PATCH] ASoC: codecs: msm8916-wcd-analog: fix module autoload
Git-commit: 46d69e141d479585c105a4d5b2337cd2ce6967e5
Patch-mainline: v4.15-rc1
References: bsc#1051510

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
