Subject: [dpdk-stable] [PATCH v2 27/38] net/sfc: free MAE lock once switch domain is assigned
Date: Mon, 11 Oct 2021 17:48:46 +0300
Message-ID: <20211011144857.446802-28-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20211011144857.446802-1-andrew.rybchenko@oktetlabs.ru>

From: Viacheslav Galaktionov <viacheslav.galaktionov@oktetlabs.ru>

If for some reason the hardware switch ID initialization function fails,
MAE lock is still held after the function finishes. This patch fixes that.

Fixes: 1e7fbdf0ba19 ("net/sfc: support concept of switch domains/ports")
Cc: stable@dpdk.org
