From 878315cbf04dde3f93bf796f1835ae8d07604ba7 Mon Sep 17 00:00:00 2001 From: Shan Hai Date: Mon, 18 Mar 2013 10:30:43 +0800 Subject: libata: Use integer return value for atapi_command_packet_set commit d8668fcb0b257d9fdcfbe5c172a99b8d85e1cd82 upstream. The function returns type of ATAPI drives so it should return integer value. The commit 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) since v2.6.39 changed the type of return value from int to bool, the change would cause all of the ATAPI class drives to be treated as TYPE_TAPE and the max_sectors of the drives to be set to 65535 because of the commit f8d8e5799b7(libata: increase 128 KB / cmd limit for ATAPI tape drives), for the function would return true for all ATAPI class drives and the TYPE_TAPE is defined as 0x01.
