Subject: drivers: net: ethernet: cpsw: change cpts_active_slave to active_slave
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e86ac13b031cf71d8f40ff513e627aac80e6b765;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drivers: net: ethernet: cpsw: change cpts_active_slave to active_slave

Change cpts_active_slave to active_slave so that the same DT property
can be used to ethtool and SIOCGMIIPHY.
