From a4f5749ba6e3f23ae4a137cee10324830db4d081 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 12 Sep 2006 20:35:49 -0700 Subject: [PATCH] libata: ignore CFA signature while sanity-checking an ATAPI device 0x848a in ID word 0 indicates CFA device iff the ID data is obtained from IDENTIFY DEVICE. For ATAPI devices, 0x848a in ID work 0 indicates valid ATAPI device. Fix sanity check in ata_dev_read_id() such that ATAPI devices reporting 0x848a in ID word 0 is not handled as error. The problem is identified by J.A. Magallon with HL-DT-ST DVDRAM GSA-4120B. Signed-off-by: Tejun Helo Cc: J.A.

Removing this prevents srp_reset_host() from failing if a reconnect scheduled from srp_completion() is already in progress, which in turn was causing crashes as both SCSI midlayer and srp_reconnect() were cancelling commands.
