Subject: [PATCH] Documentation: gpio: driver.rst: Remove gpiochip_irqchip_add mention
Date:   Mon,  5 Jul 2021 00:43:59 +0000
Message-Id: <5d1823c503629694de74ccd2d823188507c54706.1625445811.git.plr.vincent@gmail.com>

This function was removed in commit f1f37abbe6fc ("gpio: Retire the
explicit gpio irqchip code") but this mention was left behind.
Also, mention that .set_type() only has to set a line handler if the chip
is cascaded, as opposed to hierarchical.
