Currently, of_i2c_register_devices() is responsible for retaining info->of_node, but we're about to expose a function to parse I2C board info without registering the I2C device. We could possibly let this function retain ->of_node, but this approach is prone to reference leak since people will have to remember to call of_node_put() if something goes wrong between the OF node parsing and the registration step. Let's just retain the ->of_node in i2c_new_register() instead. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
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.
