Nickey Yang 881ef729dd drm/bridge: synopsys: dw-hdmi: check hdmi status in resume
HDMI status maybe incorrect in the following condition:
HDMI plug in -> system sleep ->  HDMI plug out -> system wake up.
At this time, cat /sys/class/drm/card 0-HDMI-A-1/status is connected.
There is no hpd interrupt, because HDMI is powerdown during suspend.
So we need check the current HDMI status in this case.
Test on rk3288 & rk3399.

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.
