From c16134976fb27d325ae037a8b39b537a77ba1d12 Mon Sep 17 00:00:00 2001 From: "Dr. H. Nikolaus Schaller" Date: Thu, 24 Apr 2014 23:43:36 -0700 Subject: [PATCH] Input: tca8418 - fix loading this driver as a module from a device tree Loading the tca8418 driver as a module on a device tree based system needs a MODULE_ALIAS because the driver name does not match the automatic name generation rules of a 'compatible' entry on i2c bus.
