- Atomic contexts, cansleep* calls and such fastpath/slopwpath
things.
- Defer ACPI event handler registration to late_initcall()
so IRQs do not fire in our face before other drivers have
a chance to register handlers.
- Race condition if a consumer requests a GPIO after
gpiochip_add_data_with_key() but before of_gpiochip_add()
- Probe errorpath in the dwapb driver.

Merge tag 'gpio-v4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO fixes from Linus Walleij:
"Some GPIO fixes. The ACPI stuff is probably the most annoying for
users that get fixed this time.
- Atomic contexts, cansleep* calls and such fastpath/slopwpath
things.
- Defer ACPI event handler registration to late_initcall() so IRQs do
not fire in our face before other drivers have a chance to register
handlers.
- Race condition if a consumer requests a GPIO after
gpiochip_add_data_with_key() but before of_gpiochip_add()
- Probe errorpath in the dwapb driver"

gpiolib-acpi: Register GpioInt ACPI event handlers from a late_initcall

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
