X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5cc29e3bea77092c48e5c71d792c7461e6a6c4cf;p=deliverable%2Flinux.git [NETROM]: Fix locking order when establishing a NETROM circuit. When establishing a new circuit in nr_rx_frame the locks are taken in a different order than in the rest of the stack. This should be harmless but triggers lockdep. Either way, reordering the code a little solves the issue. Signed-off-by: Ralf Baechle Signed-off-by: David S.
