[PATCH 1/3] thermal: max77620: Fix module autoload

From: Javier Martinez Canillas
Date: Fri Oct 14 2016 - 10:35:32 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/thermal/max77620_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/thermal/max77620_thermal.ko | grep alias
alias: platform:max77620-thermal
