[PATCH 6/9] platform/x86: hp-wmi: Refactor dock and tablet state fetchers
From: Darren Hart
Date: Wed Apr 19 2017 - 22:27:23 EST
From: "Darren Hart (VMware)" <dvhart@xxxxxxxxxxxxx>
Both dock and tablet use the HPWMI_HARDWARE_QUERY, but require different
masks. Rather than using two functions with magic masks, define the
masks, and use a common accessor.
