drivers/input/touchscreen/cyttsp4_core.c:2093:6-26: WARNING: Threaded IRQ with 
no primary handler requested without IRQF_ONESHOT (unless it is nested IRQ)

 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.
