Subject: [PATCH net-next 2/4] net: mana: Init gf_stats_work before potential error paths in probe
Date: Fri, 3 Apr 2026 00:09:41 -0700 [thread overview]
Message-ID: <20260403070948.9225-3-ernis@linux.microsoft.com> (raw)
In-Reply-To: <20260403070948.9225-1-ernis@linux.microsoft.com>
Move INIT_DELAYED_WORK(gf_stats_work) to before mana_create_eq(),
while keeping schedule_delayed_work() at its original location.
Previously, if any function between mana_create_eq() and the
INIT_DELAYED_WORK call failed, mana_probe() would call mana_remove()
which unconditionally calls cancel_delayed_work_sync(gf_stats_work)
in __flush_work() or debug object warnings with
CONFIG_DEBUG_OBJECTS_WORK enabled.
Fixes: be4f1d67ec56 ("net: mana: Add standard counter rx_missed_errors")
