Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.
This patch certainly doesn't cause any additional issues for me, so:

Howwever, it still doesn't allow both Cardhu's LCD panel and external HDMI port (1080p) to be active at once. If I boot with both enabled, or boot with just the LCD enabled and hot-plug HDMI, as soon as both heads are active, then some kind of display corruption starts; it looks like a clocking issue or perhaps memory underflow.
I haven't observed this issue. What kind of display corruption you mean? Did it recover after some seconds or the display in LVDS panel was always corrupted?
During my testing, I connected HDMI while booting cardhu and I can see the LVDS and HDMI working with no corruptions.

The external monitor is 1920x1200 I believe.
