From aa6ab905b2833ea74ec92fc9d40d6245ff294a07 Mon Sep 17 00:00:00 2001 From: Tang Yuantian Date: Mon, 21 Nov 2016 10:24:20 +0800 Subject: [PATCH] sata: fix sata command can not being executed bug Commit d97dc8a0 separated the non-command code into its own file which caused variable sata_curr_device can not be set to a correct value. Before commit d97dc8a0, variable sata_curr_device can be set correctly in sata_initialize(). After commit d97dc8a0, sata_initialize() is moved out to its own file. Accordingly, variable sata_curr_device is removed from sata_initialize() too. This caused sata_curr_device never gets a chance to be set properly which prevent other commands from being executed. This patch sets variable sata_curr_device properly.
