The 0001-xxxx.patch is only needed for Jammy kernel, other kernels
already merged this patch with bug #1909814.

[Impact]
The keyboard of some medion s17 series 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.

  ACPI: resources: Add DMI-based legacy IRQ override quirk
  ACPI: resources: Add one more Medion model in IRQ override quirk
