Subject: [PATCH] 8250: Fix lock warning
Date: Tue, 14 Oct 2008 11:28:39 +0100 [thread overview]
Message-ID: <20081014102839.20626.41534.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081014102821.20626.97298.stgit@localhost.localdomain>
From: Alan Cox <alan@redhat.com>
Splitting the 8250 code back up to avoid a clash with the NR_IRQS removal
patch introduced a last minute bug. Put back the additional needed lines
for the old lock init
