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 drivers/clk/samsung/clk-exynos-audss.ko | grep alias
alias: platform:exynos-audss-clk
After this patch:
$ modinfo drivers/clk/samsung/clk-exynos-audss.ko | grep alias
alias: platform:exynos-audss-clk
alias: of:N*T*Csamsung,exynos5420-audss-clockC*
