The pl330 irq may come after terminal chan, and desc is set null. It can't be avoided by disabling irq, because other chans use the common irq. If the chan is terminaled, we needn't call its callback or restart it. Change-Id: I73201eaa4dbdd09c765129f9f3f41573c73faf73 Signed-off-by: Huibin Hong <huibin.hong@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.
