From 110f66d25c33c2259b1125255fa7063ab07b8340 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 16 Sep 2009 04:17:28 +0900 Subject: libata: make gtf_filter per-dev Add ->gtf_filter to ata_device and set it to ata_acpi_gtf_filter when initializing ata_link. This is to allow quirks which apply different gtf filters.
