Warning when compiling with python3.12

[Srikar Dronamraju <srikar@xxxxxxxxxxxxxxxxxx>]

Hi,

When trying to build on v6.5-rc4 with python 3.12 aka Python 3.12.0rc1 I am
hitting the below Warning messages.

I didn't see something similar reported upstream, hence thought of reporting.

  arg_re = re.compile('((\w+ )*?(\w+|...))( (\**)(\w+))?$')

  footer = '''
/home/srikar/linux.git/scripts/bpf_doc.py:601: SyntaxWarning: invalid escape sequence '\ '
  one_arg += ' {}**\ '.format(a['star'].replace('*', '\\*'))

However I am not seeing this when using python 3.10 (Python 3.10.12) and
python 3.11 (Python 3.11.4). Note this is just a warning and Kernel build does
complete.
