leds: lp3952: Export I2C module alias information for module autoload
If the driver is built as a module, I2C module alias information is not filled so the module won't be autoloaded if the device isn't registered over ACPI. Export the I2C device table alias with MODULE_DEVICE_TABLE() macro so the information is exported in the module. Before this patch: $ modinfo drivers/leds/leds-lp3952.ko | grep alias alias: acpi*:TXNW3952:* After this patch: $ modinfo drivers/leds/leds-lp3952.ko | grep alias alias: i2c:lp3952 alias: acpi*:TXNW3952:* Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
