Subject: [PATCH 21/50] hid: usbhid: spin_lock in complete() cleanup
Date: Thu, 11 Jul 2013 17:05:44 +0800 [thread overview]
Message-ID: <1373533573-12272-22-git-send-email-ming.lei@canonical.com> (raw)
In-Reply-To: <1373533573-12272-1-git-send-email-ming.lei@canonical.com>
Complete() will be run with interrupt enabled, so change to
spin_lock_irqsave().
