Subject: 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.
|
|
|
|
Fixes: 0d82fb1127fb ("gpio: Add Realtek Otto GPIO support")
