From 76cb4fe7c0926c2c59f4a36ab169aa2d547c93d1 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 14 Aug 2006 23:00:20 -0700 Subject: [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.
