Bug description:
  [Impact]
  The keyboard of some medion laptops can't work under Linux.

  [Fix]
  Backport a upstream patch, after applying the patch, the keyboard
  will skip the irq override from the acpi resource layer, and the
  keyboard could work normally.

  [Test]
  Booting the patched kernel, use the keyboard to do the input.

  [Where problems could occur]
  The patch will skip the irq override based on the DMI info, so
  if a medion laptop which has the same DMI info and the irq 1
  needs to be overriden, this patch will introduce regression on
  the machine, but this possibility is very low. If this happens,
  we will consider to add more DMI match info in the table.


  Hello,
  Brand new laptop (Medion), keyboard is only working with the grub menu.
  Mouse is now working since 20.10 have been installed.
  Only the luminosity key are working on the keyboard.
  External usb keyboard works fine.
  I tried to install with usb keyboard disconnected but doesn't change anything.
