From f3d9f1ce079370d19b34fc9927b8b1355ac98503 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Wed, 4 May 2016 17:01:38 -0500 Subject: [PATCH] rpmsg: add helper macro module_rpmsg_driver This patch introduces the module_rpmsg_driver macro which is a convenience macro for rpmsg driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the rpmsg driver. By using this macro it is possible to eliminate a few lines of boilerplate code per rpmsg driver. Signed-off-by: Andrew F.
