+Subject: [PATCH 287/347] i2c: hix5hd2: Remove IRQF_ONESHOT
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+[ 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.
