The HP Stream 8 tablet is identical to the HP Stream 7 in terms of the PCB,
with the exception of the added SIM Card Slot. 
Therefore, I'm submitting this patch which properly initializes the audio 
and enables the headphone jack to work, just like it does in the 
HP Stream 7.

As documented in submitting-patches.rst please send patches to the 
maintainers for the code you would like to change.  The normal kernel
workflow is that people apply patches from their inboxes, if they aren't
copied they are likely to not see the patch at all and it is much more
difficult to apply patches.  You should include the maintainers for the
Intel drivers here.
