Andy,

I'm pretty sure XPS 9365 can test this.  I was going to try but 
https://patchwork.kernel.org/patch/10194503/ was not
able to compile on top of platform-x86/for-next.
That was the only one I saw at patchwork.

drivers/platform/x86/intel-vbtn.c:172:11: error: ‘ACPI_BUTTON_CLASS’ undeclared here (not in a function)
  .class = ACPI_BUTTON_CLASS,
           ^
drivers/platform/x86/intel-vbtn.c:178:2: error: unknown field ‘driver’ specified in initializer
  .driver = {
  ^
scripts/Makefile.build:316: recipe for target 'drivers/platform/x86/intel-vbtn.o' failed
make[5]: *** [drivers/platform/x86/intel-vbtn.o] Error 1

is that different than the one in your review queue?

Thanks,
