Subject: gpio: adp5588: use gpiochip data pointer
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f69255ce67b6e6f496d165b48231075262c9a225;p=deliverable%2Flinux.git

gpio: adp5588: use gpiochip data pointer

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().
