Subject: [PATCH v2] kselftest/devices/probe: Fix SyntaxWarning in regex strings for Python 3
Insert raw strings to prevent Python3 from interpreting string literals as Unicode strings
and, consequently, '\d' as an invalid escaped sequence.
Avoid the 'SyntaxWarning: invalid escape sequence '\d'' warning for Python versions greater than 3.6.
Fixes: dacf1d7a78bf ("kselftest: Add test to verify probe of devices from discoverable buses")
