-Subject: [PATCH] can: flexcan: flexcan_irq_state(): only read timestamp if
- needed
-
-The function flexcan_irq_state() checks the controller for CAN state
-changes and pushes a skb with the new state and a timestamp into the
-rx-offload framework.
-
-This patch optimizes the function by only reading the timestamp, if a
-state change is detected.
