Subject: [PATCH] stmmac: Remove spin_lock call in stmmac_get_pauseparam()
The following patch removed unnecessary spin_lock/unlock calls
in ethtool_ops callback functions. In the second and final version
of the patch one spin_lock call was left behind.

net: driver: stmicro: Remove some useless the lock protection
This introduced the following sparse warning:
drivers/net/ethernet/stmicro/stmmac/stmmac_ethtool.c:424:1: warning:
context imbalance in 'stmmac_get_pauseparam' -
different lock contexts for basic block

Hello,
Some spin_lock/unlock calls where also left behind in
stmmac_ethtool_setsettings(), I'm not sure if it was intentional?
Best regards,
Emil Goode
