Subject: [dpdk-stable] [PATCH 04/17] net/bnxt: release hwrm lock in the error case
Date: Tue,  8 Dec 2020 12:11:21 -0800
Message-ID: <20201208201134.47844-5-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20201208201134.47844-1-ajit.khaparde@broadcom.com>

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

In __bnxt_hwrm_func_qcaps, when memory allocations fails
driver is not releasing the hwrm lock. This patch fixes it
by calling hwrm_unlock in that error case.

Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF")
Cc: stable@dpdk.org
