These 3 commits from upstream allow us to have more fine grained control

Thanks!

Looks like I managed to introduce a build warning due to the unused timeout variable, let me submit a fresher version for 4.19, 4.14 and 4.9.

Only v4.19 and v4.14 required a v2, you can find both here:

https://lore.kernel.org/lkml/20220519190030.377695-1-f.fainelli@xxxxxxxxx/T/#t

Sorry about that, I will build with W=1 in the future to notice those set but unused variable warnings.

Thanks!
