Subject: [RESEND PATCH net] net: phy: micrel: Fixes FIELD_GET assertion
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@...el.com>
Signed-off-by: Divya Koppera <Divya.Koppera@...rochip.com>
