Refactor pch_panel_fitting to use local variables for crtc_hdisplay and crtc_vdisplay. This will help to adjust the hdisplay at one place when big/ultra joiner is involved. Introduce local variables crtc_hdisplay and crtc_vdisplay and update all references to adjusted_mode->crtc_hdisplay and adjusted_mode->crtc_vdisplay to use the new local variables.
