Initialize the context on open() with valid capture and output formats. It is good practice to always have valid formats internally. This solves one vb2 warning in the kernel log where the sizeimage value of the output format was 0 when requesting buffers, which is not allowed. It also simplifies the g_fmt ioctl implementations since they no longer have to check if a valid format was ever set. cedrus_prepare_format() now also validates sizeimage for the output formats, ensuring userspace can't set it to 0 since that would cause the same vb2 warning. Finally remove the sizeimage == 0 check in cedrus_try_fmt_vid_out() since cedrus_prepare_format() will now adjust this value.

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.
