[ Upstream commit cb18703c179713056bd7e3bdfc2260ab4e8658f0 ]
Fix a regression introduced by commit 9946e39fe8d0 ("ACPI: resource: skip
IRQ override on AMD Zen platforms") on MAINGEAR Vector Pro 2 systems, which
causes the built-in keyboard to not work. This restores the functionality
by adding an IRQ override.
No other IRQs were being overridden before, so this should be all that is
needed for these systems. I have personally tested this on the 15" model
(MG-VCP2-15A3070T), and I have confirmation that the issue is present on
the 17" model (MG-VCP2-17A3070T).
Fixes: 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms")
