From 8eabd02c246b808e0e27c3ee9ea17d0349efb06d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 12 Feb 2006 23:32:58 +0900 Subject: [PATCH] [PATCH] libata: make ata_dev_knobble() per-device ata_dev_knobble() unconditionally used the first device of the port to determine whether a device is bridged or not. This causes bridge limit to be incorrectly applied or unapplied for hosts with slave devices (e.g. ata_piix).
