Cover letter [patch 00/24] lib/kobject: kset_create_and_add return error clean up
Hello,
Currently, to verify if kset_create_and_add() is succeed or not, almost all subsystems with sysfs support are check up the return value against NULL, then return -ENOMEM on failure, since kset_create_and_add() always return NULL in case of anything wrong. However, kset_register() can fail due to other reasons, hence it's better to return the actual error on kset_create_and_add(), this patch series is just did that and this is inspired by Christoph in another thread:
