Sharing the same irqchip with multiple gpiochips is not a good practice. For instance, when installing hooks, we change the state of the irqchip. The initial state of the irqchip for the second gpiochip to register is then disrupted. Signed-off-by: Ludovic Desroches <ludovic.desroches@microchip.com>
Patch applied. Yours, Linus Walleij
