All child devices share the same one i2c_client, so the device resource (regmap) for the parent device may be changed when the child device initializes its own register map. So the regmap we get from dev_get_regmap() may not be what we want. Change-Id: I6b2d2d676f0406e8e78f79a308138401d6fe3b63 Signed-off-by: Wyon Bi <bivvy.bi@rock-chips.com>
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.
