From 2f50497d71e2982584d1a11d636d43eea0f992e6 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 20 Oct 2016 00:34:05 -0300 Subject: [PATCH] mailbox: sti: Fix module autoload for OF registration 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.
