This is a note to let you know that I have just added a patch titled
Subject: [PATCH 07/21] drm/radeon/kms/atom: set sane defaults in
atombios_get_encoder_mode()
to the drm-next branch of the 2.6.32+drm33-longterm tree which can be found at
http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=shortlog;h=refs/heads/drm-next
If you, or anyone else, feels it should not be added to the drm33-longterm tree,
please reply to this email not later than 8 days after this email was sent.
Thanks.

Subject: [PATCH 07/21] drm/radeon/kms/atom: set sane defaults in
atombios_get_encoder_mode()
commit c7a71fc761551dc8be8543f14a90d08cda4e77f9 upstream.
If there was no connector mapped to the encoder, atombios_get_encoder_mode()
returned 0 which is the id for DP. Return something sane instead based on
the encoder id. This avoids hitting the DP paths on non-DP encoders.
