[PATCH 0/9] Use GPIO data pointer in MFD

[PATCH 0/9] Use GPIO data pointer in MFD

[Linus Walleij]

I first planned to merge these patches through the GPIO tree
with ACKs, but I chickened out because I was too worried
about cross-tree conflicts.

Oops they were left sitting out there on a branch, not good.

It's better if you apply them to the MFD tree Lee, if you're
still OK with them (they have your ACKs already).

Thanks.

[PATCH 1/9] mfd: asic3: Use gpiochip data pointer

[Linus Walleij]

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().
