The mtk-mdp driver uses states to check if the formats have been set on the capture and output when turning the streaming on, setting controls or setting the selection rectangles. Those states are reset when 0 buffers are requested like when checking capabilities. This patch removes all format checks and set one by default as queues in V4L2 are expected to always have a format set. https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-streamon.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-ctrl.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-selection.html Signed-off-by: Francois Buergisser <fbuergisser@chromium.org> Signed-off-by: Eizan Miyamoto <eizan@chromium.org> Reviewed-by: Enric Balletbo I Serra <enric.balletbo@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.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.
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.
