The irq register and unregister calls in ppdone timeout path can result in race condition which can lead to scenarios where irqs will be enabled with no callback registered. Add vblank mutex lock to avoid such scenarios. Change-Id: I02b07b773d6b9a28c3af431eb3d8314292769f12 Signed-off-by: Krishna Manikandan <mkrishn@codeaurora.org>
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.
