Hans Verkuil 6d16d2e130 media: gspca: do not resubmit URBs when streaming has stopped 
[ Upstream commit e6f8bd59c2 ]

When streaming is stopped all URBs are killed, but in fill_frame and in
bulk_irq this results in an attempt to resubmit the killed URB. That is
not what you want and causes spurious kernel messages.

So check if streaming has stopped before resubmitting.

Also check against gspca_dev->streaming rather than vb2_start_streaming_called()
since vb2_start_streaming_called() will return true when in stop_streaming,
but gspca_dev->streaming is set to false when stop_streaming is called.

Fixes: 6992effe53 ("gspca: Kill all URBs before releasing any of them")

README 

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.
