Subject: [PATCH AUTOSEL 6.7 09/13] ACPI: resource: Skip IRQ override on ASUS ExpertBook B1502CGA

From: Michael Maltsev <mekosko@...jectyo.network>

[ Upstream commit e315e8692f7922cd1b2a26bd7a1741cc8ce77085 ]

Like the ASUS ExpertBook B1502CBA and various ASUS laptops, the
ASUS ExpertBook B1502CGA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.

	$ sudo dmesg | grep DMI
	[    0.000000] DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CGA_B1502CGA/B1502CGA, BIOS B1502CGA.303 06/05/2023
	$ grep -A 40 PS2K dsdt.dsl | grep IRQ -A 1
	                IRQ (Level, ActiveLow, Exclusive, )
	                    {1}

This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.
