Subject: [PATCH v2 net-next 0/2] net: dsa: realtek: fix PHY register read corruption

From: Alvin Šipraga <alsi@...g-olufsen.dk>

These two patches fix the issue reported by Arınç where PHY register
reads sometimes return garbage data.

v1 -> v2:

- no code changes
- just update the commit message of patch 2 to reflect the conclusion
  of further investigation requested by Vladimir

Alvin Šipraga (2):
  net: dsa: realtek: allow subdrivers to externally lock regmap
  net: dsa: realtek: rtl8365mb: serialize indirect PHY register access
