Subject: drm/radeon/kms/atom: disable the encoders in encoder_disable
X-Git-Tag: v2.6.35-rc1~18^2~77
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=aa9613916a461027fdade8661177660db0975806

drm/radeon/kms/atom: disable the encoders in encoder_disable

Previously we just set them to dpms off.  This should save
additional power.
