Sorry I didn't see the original patch (I think it disappeared
into a mail outage). Fix is good, but I think we can improve
the code further by moving the declaration down another block,
into the 'if (rc == -EPERM)', at which point it is no longer
shadowed by the other nic_data declaration in the
'else if (!rc)' block.
Alternatively, we could rename the latter to 'pf_nic_data' or
something. Any opinions/preferences on which way to go? We
could even do both...
When I make up my mind I'll spin an incremental patch.
