Whenever a display update was sent, apart from updating the memory base address, we called mcde_display_send_one_frame() which also sent a command to the display requesting the TE IRQ and enabling the FIFO. When continuous updates are running this is wrong: we need to only send this to start the flow to the display on the very first update. This lead to the display pipeline locking up and crashing. Check if the flow is already running and in that case do not call mcde_display_send_one_frame(). This fixes crashes on the Samsung GT-S7710 (Skomer).

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.
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.
