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. Signed-off-by: NZhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: NEric Anholt <eric@anholt.net>
