As warned by Coverity: CID 1415211 (#1 of 1): Unused value (UNUSED_VALUE)assigned_value: Assigning value -22 to ret here, but that stored value is overwritten before it can be used. On all cases where the there's a goto 'unlock_out' or 'streamof', ret was filled with a non-sero value. It toesn't make sense to override such error code with a videobuf_streamoff() error.

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.
