Summary: Now that clang is going to be able to build the Linux kernel again on x86, and we have gen_compile_commands.py upstream for generating compile_commands.json, clang-tidy can be used on the Linux kernel source. To that end, this commit adds a new clang-tidy module to be used for checks specific to Linux kernel source. The Linux kernel follows its own style of C, and it will be useful to separate those checks into their own module. This also adds an initial check that makes sure that return values from the kernel error functions like PTR_ERR and ERR_PTR are checked. It also makes sure that any functions that directly return values from these functions are checked.
