From 2aeac95d1a4cc85aae57ab842d5c3340df0f817f Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 11 Jun 2019 11:40:41 +0100 Subject: soundwire: add module_sdw_driver helper macro This Helper macro is for SoundWire drivers which do not do anything special in module init/exit. This eliminates a lot of boilerplate. Each module may only use this macro once, and calling it replaces module_init() and module_exit() Signed-off-by: Srinivas Kandagatla Signed-off-by: Vinod Koul --- include/linux/soundwire/sdw_type.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'include/linux/soundwire') diff --git a/include/linux/soundwire/sdw_type.h b/include/linux/soundwire/sdw_type.h index 9c756b5a0dfe..aaa7f4267c14 100644 --- a/include/linux/soundwire/sdw_type.h +++ b/include/linux/soundwire/sdw_type.h @@ -16,4 +16,15 @@ void sdw_unregister_driver(struct sdw_driver *drv); int sdw_slave_modalias(const struct sdw_slave *slave, char *buf, size_t size); +/** + * module_sdw_driver() - Helper macro for registering a Soundwire driver + * @__sdw_driver: soundwire slave driver struct + * + * Helper macro for Soundwire drivers which do not do anything special in + * module init/exit.
