The Lenovo D330 is a notebook with detachable display. The display
is installed in landscape orientation, but the display mode is in
portrait orientation. By default, the display output is rotated to
the left by 90°.
The sysfb quirk breaks the display by swapping display width and
height; and thus mixing up the display geometry. Fix this by keeping
the display as-is. The sysfb DRM drivers, usually efidrm, will pick
the correct panel orientation for the display.
The exact behavior might depend on the version of the BIOS release,
but the exact version numbers of broken and good releases are unknown.
Users are advised to update to the latest firmware.
Tested on a Lenovo D330-10IGM IdeaPad with firmware 8NCN43WW.
