uvcvideo creates a debugfs directory based on the device bus number and device number. If a device contains more than one uvc function, the creation of the second and following debugfs directories will fail and print an info message like this: "uvcvideo: Unable to create debugfs 3-2 directory." This patch includes the uvc streaming interface number in the debugfs directory name, to make sure it is unique. The directory name format is changed from "<busnum>-<devnum>" to "<busnum>-<devnum>-<intfnum>" Signed-off-by: Torleiv Sundre <torleiv@huddly.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@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.
