Subject: gpio/pca953x: Fix warning of enabled interrupts in handler
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6dd599f8af0166805951f4421a78ba716d78321a;p=linux-beck.git

gpio/pca953x: Fix warning of enabled interrupts in handler

When using nested threaded irqs, use handle_nested_irq(). This function
does not call the chip handler, so no handler is set.
