Subject: [PATCH 03/12] bnx2: Search VPD with pci_vpd_find_ro_info_keyword()
Date: Sun, 22 Aug 2021 15:50:50 +0200	[thread overview]
Message-ID: <7ca2b8b5-4c94-f644-1d80-b2ffb8df2d05@gmail.com> (raw)
In-Reply-To: <1ca29408-7bc7-4da5-59c7-87893c9e0442@gmail.com>

Use pci_vpd_find_ro_info_keyword() to search for keywords in VPD to
simplify the code.
