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
