Subject: [PATCH net-next v2 4/4] net: phy: bcm54140: add second PHY ID
Date:   Wed, 29 Apr 2020 01:06:59 +0200
Message-Id: <20200428230659.7754-4-michael@walle.cc>

This PHY has two PHY IDs depending on its mode. Adjust the mask so that
it includes both IDs.

changes since v1:
 - leave the PHY ID in brcmphy.h but clear the masked bit
 - fixed typo in commit message
