Subject: [PATCH] Input: fix irqf_oneshot.cocci warnings

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

drivers/input/misc/da7280.c:1335:7-32: ERROR: Threaded IRQ with no primary handler requested without IRQF_ONESHOT

 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.

Please take the patch only if it's a positive warning. Thanks!
