From d6a38c0ba778abd6683858bfd7c768f7edab2ebb Mon Sep 17 00:00:00 2001 From: PrasannaKumar Muralidharan Date: Thu, 25 Aug 2016 22:30:50 +0530 Subject: miscdevice: Use module_misc_device() macro This patch removes module_init()/module_exit() from driver code by using module_misc_device() macro. All modules in this patch has a print statement which is removed when module_misc_device() macro is used. If undesirable this patch can be dropped entirely, this is the only purpose of making this as a separate patch.
