[PATCH 2/3] thermal: tango: Fix module autoload

From: Javier Martinez Canillas
Date: Fri Oct 14 2016 - 10:35:48 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/tango_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/thermal/tango_thermal.ko | grep alias
alias: of:N*T*Csigma,smp8758-thermalC*
alias: of:N*T*Csigma,smp8758-thermal
