From 78f76b09c915d7281317d8e082c4c02f325a0366 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Wed, 17 Jul 2024 17:48:16 +0900 Subject: ata: libata: Move sata_std_hardreset() definition to libata-sata.c Unlike ata_std_prereset() and ata_std_postreset(), the function sata_std_hardreset() applies only to SATA devices, as its name implies. So move its definition to libata-sata.c. Together with this, also move the definition of sata_port_ops to libata-sata.c, where it belongs.
