From ca75d601b5942e8cf5eed68f308be0526d0dac5d Mon Sep 17 00:00:00 2001 From: PrasannaKumar Muralidharan Date: Thu, 25 Aug 2016 22:30:49 +0530 Subject: miscdevice: Add helper macro for misc device boilerplate Many modules call misc_register and misc_deregister in its module init and exit methods without any additional code. This ends up being boilerplate. This patch adds helper macro module_misc_device(), that replaces module_init()/ module_exit() with template functions. This patch also converts drivers to use new macro. Change since v1: Add device.h include in miscdevice.h as module_driver macro was not available from other include files in some architectures.
