From aa73684cdeb3a8a9f38e6a240b177c1fe04178b5 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 14 Oct 2016 09:23:34 -0300 Subject: [PATCH] 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.
