From: Sebastian Andrzej Siewior Date: Tue, 13 Aug 2019 12:30:37 +0200 Subject: [PATCH] i2c: hix5hd2: Remove IRQF_ONESHOT Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.17-rt9.tar.xz 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.
