I thought it applies only to the group, and id=NULL > indicating that it's a local group that was created with id=NULL (by > address match). at least in my tests, acomp_exit() ended up releasing a bunch of devres allocations made with devm_kzalloc() that had no relation to acomp. I noted that in devres.c:find_group(), docs say: /* Find devres group with ID @id. If @id is NULL, look for the latest. */ static struct devres_group * find_group(struct device *dev, void *id) ... I don't see how it would be limiting a local group.
