Subject: input: adp5589-keys: use gpiochip data pointer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=839850f4fb76b56fcad3cabe27fc9f1a03821a2c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

input: adp5589-keys: 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().
