From cdd861d68d27a0d0ebe4e641d20d8cfa5cef405f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 13 Oct 2010 09:18:53 +0000 Subject: [PATCH] ns83820: spin_lock_irq() => spin_lock() This is essentially cosmetic. At this point the IRQs are already disabled because we called spin_lock_irq(&dev->rx_info.lock). The real bug here was fixed back in 2006 in 3a10ccebe: "[PATCH] lock validator: fix ns83820.c irq-flags bug". Prior to that patch, it was a "spin_lock_irq is not nestable" type bug. The 2006 patch changes the unlock to not re-enable IRQs, which eliminates the potential deadlock. But this bit was missed. We should change the lock function as well so it balances nicely.
