[PATCH] lockdep: fix smc91x
When booting using root-nfs, I'm seeing (independently) two lockdep dumps
in the smc91x driver. The patch below fixes both. Both dumps look like
real locking issues.
Nico - please review and ack if you think the patch is correct.
Dump 1:
Sending DHCP requests .

[ INFO: inconsistent lock state ]
