ieee1394: sbp2: fix probing of some DVD-ROM/RWs
Since commit 98e238cd42be6c0852da519303cf0182690f8d9f in Linux 2.6.19, "ieee1394: sbp2: don't prefer MODE SENSE 10", some FireWire DVD-ROMs and DVD-RWs were mistaken as CD-ROM because sr_mod now sent MODE SENSE 6. The MMC command set includes only MODE SENSE 10. http://bugzilla.kernel.org/show_bug.cgi?id=7800 This fix lets sbp2 switch scsi_device.use_10_for_rw on for MMC LUs. This should rather be done in the command set driver sr_mod, not in the sbp2 transport driver, and an according patch will follow for a next Linux release.
