changeset6bbf7a855d("media: dvbdev: convert DVB device types into an enum") added a new warning on gcc 6: >> drivers/media/dvb-core/dvbdev.c:86:1: warning: control reaches end of non-void function [-Wreturn-type] That's because gcc is not smart enough to see that all types are present at the switch. Also, the current code is not too optimized. So, replace it to a more optimized one, based on a static table.

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.
