Hi, Andrew. Thank you for your review and feedback on both this and
previous version.

I wanted to make those functions generic and not introduce new functions
other than 6321_serdes_get_lane. However, those functions cannot be
generalised the obvious way because they run with reg_lock already taken
which would cause deadlock in mv88e6352_serdes_get_lane function.

Do you have proposal on how that problem can be avoided to make these
functions generic, too?

Best,
Fidan
