------------------------------------------------------
Subject: libata: don't fail ata device revalidation for bad _GTF methods
From: Matthew Garrett <mjg59@srcf.ucam.org>

Experience suggests that the _GTF method may be bad.  We currently fail
device revalidation in that case, which seems excessive.
