Subject: REGRESSION on linux-next (next-20260115)
Hello all,
Hope you are doing well. I am Chaitanya from the linux graphics team in
Intel.
This mail is regarding a regression we are seeing in our CI runs[1] on
linux-next repository.
Since the version next-20260115 [2], we are seeing the following regression

commit aef30c8d569c0f31715447525640044c74feb26f
Author: Sebastian Andrzej Siewior bigeasy@...utronix.de
Date: Mon Jan 12 14:40:13 2026 +0100
genirq: Warn about using IRQF_ONESHOT without a threaded handler
`````````````````````````````````````````````````````````````````````````````````````````````````````````
Looking at the irq register code in int0002_vgpio.c, it seems the
warning comes from
ret = devm_request_irq(dev, irq, int0002_irq,
IRQF_ONESHOT | IRQF_SHARED, "INT0002",
chip);
Looking at the history, this flag was added by the Commit 8f812373d195
("platform/x86: intel: int0002_vgpio: Pass IRQF_ONESHOT to
request_irq()") to resolve another issue.
Any proposals for solving the WARN_ON?
Thank you.
Regards
Chaitanya
