Do you really want to delay the work on disable?

Wouldn't it be better to use a delay worker for the enablement and in
the disable case you cancel the work and just disable_irq() directly
here.
Sure. Will do it in the next series.

But more importantly, if this is only related to auto detection, do you
really want to enable/disable the ovp_irq after you have detected the
string configuration?
Ok. This is used for the genuine OVP detection and for the auto detection as
well.
What is the expected outcome of detecting an OVP condition, outside auto
detection?
