…mmon.py (#698) #### Description Updated regex patterns `p1` and `p2` in `PcieUtil.get_pcie_device()` to use raw string literals (`r"..."`) instead of plain string literals. #### Motivation and Context Python 3.12+ emits `DeprecationWarning` for invalid escape sequences in regular string literals (e.g., `\w`, `\s`, `\(`), and Python 3.13 raises a `SyntaxWarning` for these. Without raw strings, sequences like `\w` and `\s` are technically undefined escape sequences that happen to work today but will become `SyntaxError` in a future Python release. Using raw string literals (`r"..."`) is the correct and idiomatic way to write regex patterns in Python. #### How Has This Been Tested? - Verified the existing test suite passes: `pytest tests/pcie_common_test.py -v` - Confirmed no `DeprecationWarning` or `SyntaxWarning` is emitted under Python 3.12/3.13 - No behavioral change, the regex patterns themselves are identical #### Additional Information (Optional) This is a purely cosmetic/correctness fix. The regex logic and matched groups are unchanged. Signed-off-by: Sonic Build Admin <sonicbld@microsoft.com>
