Subject[PATCH 2/2] mailbox: sti: Fix module autoload for OF registration
Date
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/mailbox/mailbox-sti.ko | grep alias
alias: platform:mailbox-sti

After this patch:

$ modinfo drivers/mailbox/mailbox-sti.ko | grep alias
alias: platform:mailbox-sti
alias: of:N*T*Cst,stih407-mailboxC*
alias: of:N*T*Cst,stih407-mailbox
