[alsa-devel] [PATCH 177/182] ASoC: wm5100: 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().

Liam/Mark: please ACK this so I can merge it into the GPIO tree.

I guess you probably still want an ack from Mark before applying to the GPIO tree but for what is worth looks fine to me.
Thanks, Charles
