The maximum alpha is 255, but after the product of color and alpha in the blend formula, the final result is >> 8 (/256) instead of /255, which will introduce errors. This fix is that when alpha is 0x80~0xff, then +1. Signed-off-by: Yu Qiaowei <cerf.yu@rock-chips.com> Change-Id: Ibba964f29a11eb226aa008a0dd5bf89048524b43

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.
