From 09fd0de5bd8f8ef3317e5365f92f1a13dcd89aa9 Mon Sep 17 00:00:00 2001 From: "Gustavo F. Padovan" Date: Fri, 17 Jun 2011 13:03:21 -0300 Subject: [PATCH] Bluetooth: Replace spin_lock by mutex in hci_dev Now we run everything in HCI in process context, so it's a better idea use mutex instead spin_lock. The macro remains hci_dev_lock() (and I got rid of hci_dev_lock_bh()), of course. Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.
