This is a good point. I think I will leave the active_interrupts as they
are and instead re-enable the hrtimer. That was one of the two solutions
I was thinking about. This should also fix the last point sashiko made.

>> - [Medium] can: tcan4x5x: unbalanced enable_irq_wake() when m_can_class_suspend() fails

True, should be a follow-up fix. This is already what happens now
without the patch. The patch doesn't change this behavior but also
doesn't fix it.

Thanks I didn't get these.

Also I am wondering why sashiko didn't flag any of this on my patch
submission...
