firewire: get_cycle_timer optimization and cleanup
ohci: Break out of the retry loop if too many attempts were necessary. This may theoretically happen if the chip is fatally defective or if the get_cycle_timer ioctl was performed after a CardBus controller was ejected. Also micro-optimize the loop by re-using the last two register reads in the next iteration, remove a questionable inline keyword, and shuffle a comment around. core: ioctl_get_cycle_timer() is always called with interrupts on, therefore local_irq_save() can be replaced by local_irq_disable(). Disabled local IRQs imply disabled preemption, hence preempt_disable() can be removed. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
