I tried it with grep (maybe it is wrong) and it finds only files with
underscores.

➜  kernel git:(m/xfrm-latest) tree | grep -E "(?:\b|_)ptp(?:\b|_)"
│   │   │   │   │   ├── ice_ptp_consts.h
│   │   │   │   │   ├── ice_ptp_hw.c
│   │   │   │   │   ├── ice_ptp_hw.h

And this is as it is written in MAINTAINERS without "_".

➜  kernel git:(m/xfrm-latest) tree | grep -E "\bptp\b"

Should I try it differently?
