This was made apparent by what appeared to be a regression in the mainline kernel that started introducing suspend/resume issues for nouveau:

I'm just a dumb user here, but I confirm: CPU: AMD Phenom II X6 1055T, GPU: GTX 560 Ti 100% fail to resume GPU on 4.15-rc*, 100% ok with your patch.

And that spinning rust hates being repeatedly powered off and on... :/

Changes since v2:

• Remove teardown, just reuse pci->irq to indicate when we're tearing down the driver
