From 6d8d271eee0eaa3c3ffd6db29a825e02316359d4 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 18 Oct 2016 17:44:01 -0300 Subject: [PATCH] gpio: ath79: 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.
