But I've splittet the patch. > Also can you please add signed-off-by lines to your patch when > resubmitting? See Documentation/SubmittingPatches for all the details. The patch already had a "Signed-off-by" line. The checkpatch script complains that it doesn't like the formatting of the CMD command. However I won't change that in this patch, as this is how the whole file is formatted. If this is wanted I can submit a patch changing the formatting afterwards, but I think this is an unrelated change. Please apply. --=20 Hanno B=C3=B6ck http://hboeck.de/ mail/jabber: hanno@hboeck.de GPG: BBB51E42 --MP_/A1Ne67kSwEEO5eqcd+WzT.F Content-Type: text/x-patch Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename=01-i915-fix-cmd-order.patch Properly sort cmd tables.
