Backport the patch queued upstream for 5.16. The patch differs slightly from the upstream patch due to an upstream change that added a convenience function. Signed-off-by: Sander Vanheule <sander@svanheule.net>

gpio: realtek-otto: fix GPIO line IRQ offset
|
|
|
|
The irqchip uses one domain for all GPIO lines, so th line offset should be
|
|
determined w.r.t. the first line of the first port, not the first line of the
|
|
triggered port.
