That's not really something supportable in the long term.
The number of kernel commits that are necessary to support new features will only increase
and as we move to newer kernel versions the changes get harder to backport.
Really the commit in the 4.9 tree (specifically the "Here is the big USB, and PHY, and extcon, patchsets for 4.9-rc1" merge) that causes the regression needs to be found by someone who can reproduce it.
It occurs on multiple platforms so should be possible to bisect the kernel tree on, say, x86 linux and fix the problem for good.
This thread looked promising for finding a solution but never quite got there.
