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/staging/media/s5p-cec/s5p-cec.ko | grep alias
$
After this patch:
$ modinfo drivers/staging/media/s5p-cec/s5p-cec.ko | grep alias
alias: of:N*T*Csamsung,s5p-cecC*
alias: of:N*T*Csamsung,s5p-cec
