    ACPI: resource: Skip IRQ override on ASUS ExpertBook B1502CGA · e315e869
    Michael Maltsev authored
    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.
