You probably want this patch as well, at least the first hunk....
It fixes a potential memory leak that could cause lock-ups when using
hdparm or smartctl/smartd.

Fix a few problems seen with the passthru branch:
- leaked scsi_request on buffer allocate failure
- passthru sense routines were refering to tf->command
which is not read in tf_read, instead use drv_stat for
status register.
- passthru sense passed back to user on ata_task_ioctl
Patch is against the current libata-dev passthru branch.
