ODR switch is done in 2 steps when FIFO is on : change the ODR register value and acknowledge change when reading the FIFO ODR change flag. When we are switching to the same odr value, we end up waiting for a FIFO ODR flag that is never happening. Fix the issue by doing nothing and exiting properly when we are switching to the same ODR value.
