Subject: mfd: tps65010: Use gpiochip data pointer
X-Git-Tag: android-x86-7.1-r1~1449^2~34
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=22e5e747e71f19ac3af60ce648f4c02c63ed3cc1;p=android-x86%2Fkernel.git

mfd: tps65010: 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().
