From 70412cfa6ddebcc01e6b01b3fccb6068e48596ac Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Thu, 21 Jan 2016 15:10:18 -0800 Subject: [PATCH] drm/kms_helper: Add a common place to call init and exit functions. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The module_init and module_exit functions will start here, and call the subsequent init's and exit's. v10: - Keep __init on drm_fb_helper init function. - Move MODULE_* macros to the common file.
