libata: ATA_12/16 doesn't fall into ATAPI_MISC
SAT passthrus don't really fit into ATAPI_MISC class. SAT passthru commands always transfer multiple of 512 bytes and variable length response is not allowed. This patch creates a separate category - ATAPI_PASS_THRU - for these. This fixes HSM violation on "hdparm -I". Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
