With an unknown sensor, norm_maxw() and norm_maxh() return 0 as max. height and width values, which causes a devide by zero in size_to_scale(). Of course we could use speculative default values for unknown sensors, but the chance that the device works at this resolution without any driver/setup is very low and therefore not worth the efforts. Instead, just don't treat the device as camera. A message will then be printed to the log that the device isn't supported.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
