From: Niklas Cassel Date: Wed, 3 Jul 2024 18:44:22 +0000 (+0200) Subject: ata: libata-core: Remove local_port_no struct member X-Git-Tag: v6.11-rc1~151^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1dd63a6b573ffb989ca618e60b6469f885454606;p=thirdparty%2Fkernel%2Flinux.git ata: libata-core: Remove local_port_no struct member ap->local_port_no is simply ap->port_no + 1. Since ap->local_port_no can be derived from ap->port_no, there is no need for the ap->local_port_no struct member, so remove ap->local_port_no.
