commit c23de7ceae59e4ca5894c3ecf4f785c50c0fa428 upstream.
If the directory passed to the '.. kernel-feat::' directive does not exist or the get_feat.pl script does not find any files to extract features from, Sphinx will report the following error:
Sphinx parallel build error: UnboundLocalError: local variable 'fname' referenced before assignment make[2]: *** [Documentation/Makefile:102: htmldocs] Error 2
This is due to how I changed the script in c48a7c44a1d0 ("docs: kernel_feat.py: fix potential command injection"). Before that, the filename passed along to self.nestedParse() in this case was weirdly just the whole get_feat.pl invocation.
We can fix it by doing what kernel_abi.py does -- just pass self.arguments[0] as 'fname'.
