Subject: [PATCH 60/80] tty: extract the pty init time special cases
Date: Mon, 13 Oct 2008 10:42:39 +0100 [thread overview]
Message-ID: <20081013094234.21645.93647.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081013092758.21645.2359.stgit@localhost.localdomain>
From: Alan Cox <alan@redhat.com>
The majority of the remaining init_dev code is pty special cases. We
refactor this code into the driver->install method.
