From f9cf3b2880cc41ec2b44aa24fa156bffe934f9c7 Mon Sep 17 00:00:00 2001 From: "Darren Hart (VMware)" Date: Wed, 19 Apr 2017 17:03:38 -0700 Subject: [PATCH] platform/x86: hp-wmi: Refactor dock and tablet state fetchers 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.
