[PATCH RT 04/25] i2c: hix5hd2: Remove IRQF_ONESHOT

[zanussi]

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

v4.14.170-rt75-rc1 stable review patch.
If anyone has any objections, please let me know.

-----------


[ Upstream commit e88b481f3f86f11e3243e0808a830e5ca5782a9d ]

The drivers sets IRQF_ONESHOT and passes only a primary handler. The IRQ
is masked while the primary is handler is invoked independently of
IRQF_ONESHOT.
With IRQF_ONESHOT the core code will not force-thread the interrupt and
this is probably not intended. I *assume* that the original author copied
the IRQ registration from another driver which passed a primary and
secondary handler and removed the secondary handler but keeping the
ONESHOT flag.

Remove IRQF_ONESHOT.
