From 1a433156f99f811773a3811da5c394e3ba6ad4e3 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 2 Jan 2017 11:57:20 -0300 Subject: [PATCH 1/1] tty: serial: msm: Fix module autoload commit abe81f3b8ed2996e1712d26d38ff6b73f582c616 upstream. 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.
