A quick grep found similar patterns that could have the same issue.
I think we should validate it->options[1] before shifting, right?

Thanks.
That looks fine. If you plan to submit an official patch, please Cc it
to Greg KH because I do not have commit access to any pulled git repos.
The Fixes: line for this is as follows:
Fixes: 729988507680 ("staging: comedi: das16m1: tidy up the irq support
in das16m1_attach()"
Can also add:
Cc: <stable@vger.kernel.org> # 5.13+
(Comedi moved out of staging in 5.13, so a backport is required for
earlier longterm series.)
If you don't want to deal with it, let me know, and I'll send the patch
and credit you with a 'Suggested-by' tag, or something more explicit
with your permission.

Thank you for taking a look and suggesting appropriate tags.
Unfortunately I don't have the bandwidth to prepare an official patch at the

(To be honest, I think someone who knows this driver better than me would
write a superior patch.)
