[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 ] Signed-off-by: Jeff Garzik <jeff@garzik.org>
