From c7ef144c12033052c956ca9d80b2dfc19c73d939 Mon Sep 17 00:00:00 2001 From: "Darren Hart (VMware)" Date: Wed, 19 Apr 2017 18:00:01 -0700 Subject: [PATCH] platform/x86: hp-wmi: Cleanup wireless get_(hw|sw)state functions Use the new hp_wmi_read_int() function and add a WARN_ONCE() to the TBD regarding passing the error through. These are used in a null return function unfortunately.
