Merge branch 'dsa-dont-unmask-port-bitmaps'
Vivien Didelot says:
====================
net: dsa: don't unmask port bitmaps
DSA has several bitmaps to store the type of ports: cpu_port_mask,
dsa_port_mask and enabled_port_mask. But the code is inconsistently
unmasking them.
The legacy code tries to unmask cpu_port_mask and dsa_port_mask but
skips enabled_port_mask.
The new bindings unmasks cpu_port_mask and enabled_port_mask but skips
dsa_port_mask.
In fact there is no need to unmask them because we are in the error
path, and they won't be used after. Instead of fixing the unmasking,
simply remove them.
