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

Any comments about this patch and 2/2? Lee acked both patches but
I see that were never picked.
