Subject: [dpdk-dev] [PATCH v2 07/25] net/bnxt: add null pointer check for resource manager
Date: Tue, 15 Sep 2020 21:28:33 -0700
Message-ID: <20200916042851.32914-8-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200916042851.32914-1-ajit.khaparde@broadcom.com>

From: Shahaji Bhosle <sbhosle@broadcom.com>

Verify the resource manager has been allocated prior to using it.
This can avoid potential segmentation faults.
