From: Zhenyu Wang Date: Tue, 30 Mar 2010 06:39:31 +0000 (+0800) Subject: drm/i915: change intel_ddc_get_modes() function parameters X-Git-Tag: v2.6.35-rc1~18^2~98^2~40 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=335af9a235a82842854b394507ab5e310d88be42;p=platform%2Fkernel%2Flinux-3.10.git drm/i915: change intel_ddc_get_modes() function parameters This one replaces original param for intel_ddc_get_modes() with DRM connector and i2c bus adapter instead. With explicit params, we won't require that a single driver structure must hold connector and DDC bus reference, which ease the conversion to splitted encoder/ connector model. It also clears up for some cases that we would steal other DDC bus for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed a bug in old DVI-I probe handling, that failed to restore origin analog GPIO port.
