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 <srinivas.kandagatla@linaro.org> --- include/linux/soundwire/sdw_type.h | 11 +++++++++++ 1 file changed, 11 insertions(+) -- 2.21.0 _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
