[PATCH 4/4] power: reset: zx-reboot: Fix module autoload

From: Javier Martinez Canillas
Date: Mon Oct 17 2016 - 14:37:14 EST


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/power/reset/zx-reboot.ko | grep alias
$

After this patch:

$ modinfo drivers/power/reset/zx-reboot.ko | grep alias
alias: of:N*T*Czte,sysctrlC*
alias: of:N*T*Czte,sysctrl
