Subject: [PATCH AUTOSEL 6.5 23/31] ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to irq1_edge_low_force_override[]

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit f9b3ea02555e67e2e7bf95219953b88d122bd275 ]

The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.

The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.

Adjust the pcspecialist_laptop[] DMI match table for this:

1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
   entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
   the laptop when sold by other vendors such as hyperbook.pl.

2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
   models.

Note the .ident values of the dmi_system_id structs are left unset
since these are not used.
