Subject: [PATCH] rtc: max77686: fix irqf_oneshot.cocci warnings

From: kbuild test robot <fengguang.wu@...el.com>

 Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
 threaded IRQs without a primary handler need to be requested with
 IRQF_ONESHOT, otherwise the request will fail.

 So pass the IRQF_ONESHOT flag in this case.
