Davis" List-ID: 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.
