Subject[PATCH 1/2] mailbox: mailbox-test: Fix module autoload
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-test.ko | grep alias
$

After this patch:

$ modinfo drivers/mailbox/mailbox-test.ko | grep alias
alias: of:N*T*Cmailbox-testC*
alias: of:N*T*Cmailbox-test
