clocksource/drivers/mips-gic-timer: Remove pointless irq_save,restore
The function gic_next_event is always called with interrupts disabled, so the local_irq_save / local_irq_restore are pointless - remove them. [Daniel Lezcano: Fixed warning by removing unused variable 'flags'] Signed-off-by: Matt Redfearn <matt.redfearn@mips.com> Suggested-by: Daniel Lezcano <daniel.lezcano@linaro.org> Reported-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
