[PATCH] gpio: Do not include <linux/kernel.h> when not really needed.

[Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>]

<linux/kernel.h> is included only for using container_of().
Include <linux/container_of.h> instead, it is much lighter.

Not sure if the prefix should be gpio or gpiolib.

Let see if build-bots spot something which is inherit via kernel.h
