Subject: [PATCH 287/329] i2c: hix5hd2: Remove IRQF_ONESHOT
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.135-rt60.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.
