Subject: [PATCH net] net: phy: micrel: Fixes FIELD_GET assertion
Date: Mon, 3 Oct 2022 12:01:30 +0530 [thread overview]
Message-ID: <20221003063130.17782-1-Divya.Koppera@microchip.com> (raw)
FIELD_GET() must only be used with a mask that is a compile-time
constant. Mark the functions as __always_inline to avoid the problem.
Fixes: 21b688dabecb6a ("net: phy: micrel: Cable Diag feature for lan8814 phy")
Reported-by: kernel test robot <lkp@intel•com>
