But I really want to get rid of this line and
vacate the work-queue, so that in the future the
per-driver work-queues can be replaced with this.
Why do you think it is still needed?
Are there any valid cases where you need to disable the
soft-blink from hard-irq context? IMHO the soft-blink is
only disabled as a result of user's actions, which is not
in a hard-irq context.
Could you please explain the use-case?

Indeed, but with these changes there should be no requirement
for disabling a soft-blink from hard-irq context, which is what
I really wanted to have. What am I missing?
