Please do not do this. adjusted_mode is already available in crtc->hwmode.

Please also restructure this driver to use the atomic infrastructure.
A good example of how to do this can be found in the Rockchip RK3288
driver which was submitted a while ago: it started off as a legacy
driver like this, but was converted during the submission phase.

I'm sure there are many more comments to come, but certainly
converting to be an atomic driver is the very first step.
