Subject: [PATCH 4/5] cxgb3: Use VPD API in t3_seeprom_wp()
Date: Fri, 10 Sep 2021 08:25:49 +0200	[thread overview]
Message-ID: <f768fdbe-3a16-d539-57d2-c7c908294336@gmail.com> (raw)
In-Reply-To: <ba0b18a3-64d8-d72f-9e9f-ad3e4d7ae3b8@gmail.com>

Use standard VPD API to replace t3_seeprom_write(), this prepares for
removing this function. Chelsio T3 maps the EEPROM write protect flag
to an arbitrary place in VPD address space, therefore we have to use
pci_write_vpd_any().
