45e8bd9cdc gpio: da905x: Include proper header
These drivers has no business including <linux/gpio.h>, they
are drivers so include <linux/gpio/driver.h>.

e35b5ab0a7 gpio: constify gpio_chip structures
These structures are only used to copy into other structures, so declare
them as const.

The semantic patch that makes this change is as follows:

7e9104ccb3 gpio: da9055: Use devm_gpiochip_add_data() for gpio registration
Use devm_gpiochip_add_data() for GPIO registration and remove the
need of driver callback .remove.

552dd7959c gpio: da9055: 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().

4a3a950ee9 gpio: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

9fb1f39eb2 gpio/pinctrl: make gpio_chip members typed boolean
This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

0fe763c570 Drivers: misc: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
