Please note that there is a follow-on patch, also from Shanker, that
fixes this patch (it was slightly mangled when merged into 4.16-rc1):

https://www.spinics.net/lists/arm-kernel/msg633726.html

I would love for it to be included in 4.14.20, but it hasn't been
merged into Linus' tree yet.  I will send a patch request when it does
land in 4.16-rc2.
