PM / devfreq: exynos-ppmu: Fix module autoload
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/devfreq/event/exynos-ppmu.ko | grep alias $ After this patch: $ modinfo drivers/devfreq/event/exynos-ppmu.ko | grep alias alias: of:N*T*Csamsung,exynos-ppmu-v2C* alias: of:N*T*Csamsung,exynos-ppmu-v2 alias: of:N*T*Csamsung,exynos-ppmuC* alias: of:N*T*Csamsung,exynos-ppmu Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>
