From: Nicolas Dechesne nicolas.dechesne@linaro.org
[ Upstream commit 46d69e141d479585c105a4d5b2337cd2ce6967e5 ]
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
