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(+)
