Currently the code deals with uevents at the bus level, but we only care for Slave events
What does this mean? I can't understand it, can you please provide more information on what you are doing here?
In the earlier versions of the patch, the code looks like this and there was an open on what to do with a master-specific event.
static int sdw_uevent(struct device *dev, struct kobj_uevent_env *env) {
- struct sdw_master_device *md; struct sdw_slave *slave; char modalias[32];
- if (is_sdw_slave(dev)) {
- if (is_sdw_md(dev)) {
md = to_sdw_master_device(dev);/* TODO: do we need to call add_uevent_var() ? */- } else if (is_sdw_slave(dev)) { slave = to_sdw_slave_device(dev);
sdw_slave_modalias(slave, modalias, sizeof(modalias));if (add_uevent_var(env, "MODALIAS=%s", modalias))return -ENOMEM;Vinod suggested this was not needed and suggested the code for uevents be moved to be slave-specific, which is what this patch does.
Then describe it really really well in the changelog text. We have no rememberance of prior conversations when looking at commits in the tree in the future.
