Subject: [dpdk-dev] [PATCH 2/3] net/bnxt: fix error path handling of dev start op
Date: Thu, 24 Dec 2020 15:07:33 +0530 [thread overview]
Message-ID: <20201224093734.13940-3-somnath.kotur@broadcom.com> (raw)
In-Reply-To: <20201224093734.13940-1-somnath.kotur@broadcom.com>
Call bnxt_dev_stop in error path of bnxt_dev_start_op() to keep
it simple and consistent
Fixes: c09f57b49c13 ("net/bnxt: add start/stop/link update operations")
