From f42cce3c2409960adebe8e970574b23cbbf34e7d Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 20 Oct 2016 00:34:04 -0300 Subject: [PATCH] mailbox: mailbox-test: 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.
