From: Heiner Kallweit Date: Fri, 10 Sep 2021 06:25:49 +0000 (+0200) Subject: cxgb3: Use VPD API in t3_seeprom_wp() X-Git-Tag: v6.6.17~8838^2~16^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43f3b61e37e03ae917ffd62395478efb4fa4eb50;p=platform%2Fkernel%2Flinux-rpi.git cxgb3: Use VPD API in t3_seeprom_wp() 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().
