4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Martinez Canillas <javier@osg.samsung.com>
[ Upstream commit a93151a72061e944a4915458b1b1d6d505c03bbf ]
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/platform/x86/intel_mid_thermal.ko | grep alias $
After this patch:
$ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias alias: platform:msic_thermal
