Commit 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation") has made the cherryview gpio numbers sparse, to get a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux. This has greatly simplified things, but the code setting the irq_valid_mask was not updated for this, so the valid mask is still in the old "compressed" numbering with the gaps in the pin numbers skipped, which is wrong as irq_valid_mask needs to be expressed in gpio numbers. This results in the following error on devices using pin 24 (0x0018) on the north GPIO controller as an ACPI event source: [ 0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ This has been reported (by email) to be happening on a Caterpillar CAT T20 tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1. This commit uses the pin number instead of the compressed index into community->pins to clear the correct bits in irq_valid_mask for GPIOs using GPEs for interrupts, fixing these errors and in case of the Medion Akoya e2215t also fixing the LID switch not working.
