From 983e20cfdcb6e08b3560071a147169f3a1be4391 Mon Sep 17 00:00:00 2001 From: Vegard Nossum vegard.nossum@oracle.com Date: Mon, 5 Feb 2024 18:51:26 +0100 Subject: [PATCH] docs: kernel_feat.py: fix build error for missing files

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'.
