Subject: [PATCH] kernel: time: Return ENXIO instead of ENODEV when call smp_call_function_single fail in clockevents_unbind
Date: Sun, 19 Dec 2021 23:29:29 +0800 [thread overview]
Message-ID: <20211219152929.479876-1-gchen@itskywalker.com> (raw)
From: Chen Gang <gchen@itskywalker.com>
smp_call_function_single will return -ENXIO for failure, so ENXIO needs
to be as the default value of cu.res for return instead of ENODEV.
