Ding Wei 4e57d971b6 video: rockchip: mpp: rcu_read_lock/unlock -> device_links_read_lock/unlock 
reason:
1. might_sleep is called by pm_runtime_xx, thus, it cannot covered by
   rcu_read_lock/unlock which is atomic context.
2. it need use device_links_read_lock/unlock when meets dev->links.suppliers.

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.
