From cfde6c872ae02650020158befd45f36a22c97fef Mon Sep 17 00:00:00 2001 From: Florian Schmaus Date: Tue, 20 Feb 2024 08:52:48 -0500 Subject: [PATCH] pylibfdt: Fix "invalid escape sequence '\w'" in setup.py Once u-boot's build system invokes python3 scripts/dtc/pylibfdt/setup.py --quiet build_ext --inplace it may fail with scripts/dtc/pylibfdt/setup.py:40: SyntaxWarning: invalid escape sequence '\w' RE_KEY_VALUE = re.compile('(?P\w+) *(?P[+])?= *(?P.*)$') depending on the used Python version. Explicitly mark the regex string as raw string to avoid the warning.
