Hi YueHaibing, Thank you for the patch! Perhaps something to improve:

This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of atalk_proc_exit() so it may be used outside an exit section. --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/pipermail/kbuild-all Intel Corporation
