Use gpiod_set_value_cansleep in the init_device function. Without this change, the driver may print a warning if the LP55xx enable pin is connected to a GPIO chip which can sleep (e.g. a GPIO expander): WARNING: CPU: 0 PID: 2719 at drivers/gpio/gpiolib.c:3051 gpiod_set_value+0x64/0xbc Signed-off-by: Stefan Eichenberger <eichest@gmail.com> Link: https://lore.kernel.org/r/20230918143238.75600-1-eichest@gmail.com Signed-off-by: Lee Jones <lee@kernel.org>
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.
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.
