Subject: [PATCH RT 01/32] i2c: exynos5: Remove IRQF_ONESHOT
Date: Fri, 17 Jan 2020 12:41:12 -0500 [thread overview]
Message-ID: <20200117174127.480853193@goodmis.org> (raw)
In-Reply-To: 20200117174111.282847363@goodmis.org
4.19.94-rt39-rc1 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
[ Upstream commit 4b217df0ab3f7910c96e42091cc7d9f221d05f01 ]
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.
