dm: add helper macro for simple DM target module init and exit 2023-04-11T16:09:08+00:00 Yangtao Li frank.li@vivo.com 2023-04-09T16:43:37+00:00 3664ff82dae1ef9f14f7763d3dd30565e7ef9e14 Eliminate duplicate boilerplate code for simple modules that contain a single DM target driver without any additional setup code. Add a new module_dm() macro, which replaces the module_init() and module_exit() with template functions that call dm_register_target() and dm_unregister_target() respectively.
