Subject: [PATCH 1/5] clocksource/drivers/imx-sysctr: drop IRQF_IRQPOLL
From: Peng Fan <peng.fan@....com>
Per the Documentation,
IRQF_IRQPOLL is used for polling (only the interrupt that is registered
first in a shared interrupt is considered for performance reasons)
But this timer is not sharing interrupt line with others, and
actually irqpoll not work with this timer with IRQF_IRQPOLL set, so
drop the flag.
