#1502116 — [PATCH 4/5] [media] s5p-cec: Fix module autoload

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
