From: Vladislav Bolkhovitin <vst@xxxxxxxx>
Currently it is impossible to reset provided by Qlogic QLA2xxx driver
SCSI devices externally using corresponding sg devices, particularly via
sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset()
function checks if the input scsi_cmnd has its private data (CMD_SP())
attached. Then the found pointer isn't used anywhere inside of
qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it
doesn't have such private data.
The attached patch removes check for non-NULL CMD_SP() from
qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using
corresponding sg devices.
AV: change applies to bus/host reset handlers as well.
