From 9514dff918b947ae43b66517dc90d0e05548bd6a Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Sun, 18 May 2008 15:40:00 -0600 Subject: [PATCH] Remove the lock_kernel() call from chrdev_open() All in-kernel char device open() functions now either have their own lock_kernel() calls or clearly do not need one.
