When reset GPIO was missing, the driver was still printing an info message and still trying to assert the reset. Although gpiod_set_value() will silently ignore calls with NULL gpio_desc, it is better to make it clear the driver might allow gpio_desc to be NULL. The initial value for the reset pin was changed to GPIOD_OUT_LOW, followed by a gpiod_set_value() asserting the reset. This way, it will be easier to spot if and where the reset really happens. A new "asserted RESET" message was added just after the reset is asserted, similar to the existing "deasserted RESET" message. Both messages were demoted to dbg. The code comment is not needed anymore. Signed-off-by: Luiz Angelo Daros de Luca <luizluca@gmail.com> Acked-by: Arınç ÜNAL <arinc.unal@arinc9.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
