Subject: [PATCH v2 3/7] drivers/comedi: fix Python string escapes
Date:   Tue, 12 Sep 2023 16:07:57 +1000
Message-ID: <20230912060801.95533-4-bgray@linux.ibm.com>
In-Reply-To: <20230912060801.95533-1-bgray@linux.ibm.com>
References: <20230912060801.95533-1-bgray@linux.ibm.com>
MIME-Version: 1.0

Precedence: bulk

Python 3.6 introduced a DeprecationWarning for invalid escape sequences.
This is upgraded to a SyntaxWarning in Python 3.12, and will eventually
be a syntax error.

Fix these now to get ahead of it before it's an error.
