Nickey Yang 0b8aec3f03 drm: rockchip: rk628: Fix reading 4block EDID for hdmi
After the current driver had read the EDID of 4block once,
hdmi->i2c->segment cannot reset to zero, which will cause the
data when restart reading to be block2 data not the expected
block0 data.
   At the same time, when msg->addr equal to DDC_SEGMENT_ADDR,
the next setting the same EDID related register, which will lead
to repeated reading of the data of block2, but unable to read the
address of block3.

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.
