Subject: [PATCH net-next v4 08/13] net: mana: do not bail out of mana_detach on dealloc failure
Date: Mon,  7 Sep 2026 20:28:38 -0700	[thread overview]
Message-ID: <20260908032843.397667-9-longli@microsoft.com> (raw)
In-Reply-To: <20260908032843.397667-1-longli@microsoft.com>

From: Dipayaan Roy <dipayanroy@linux.microsoft.com>

Remove the early return after mana_dealloc_queues() so detach continues
its device and port-context cleanup.

The return is currently unreachable: mana_dealloc_queues() only rejects
an up port, and mana_detach() clears port_is_up before calling it. This
is a robustness cleanup, not a fix for a reachable reset failure.

Signed-off-by: Dipayaan Roy <dipayanroy@linux.microsoft.com>
Signed-off-by: Long Li <longli@microsoft.com>
---
Changes in v4:
  - Frame this as removal of an unreachable error return, not a fix
    for a reachable fatal reset failure.
