No.

I mean that suspend generally works in 4.14 and is currently broken
in 4.15-rc which requires a fix to be applied.  The fix in question is at:

https://lkml.org/lkml/2017/11/30/546

This is needed due to some changes made in 4.15-rc (with respect to 4.14)
that broke resume from suspend to RAM.
