[PATCH] libata: change order of _SDD/_GTF execution (resend #3)
Make the sdd call come before gtf. _SDD is used to provide input to the _GTF file, so it should be executed first. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> (cherry picked from 89d74215e1e5b79ea084385b5c83d0e33cf2d655 commit)
