From 751ae808f6b29803228609f51aa1ae057f5c576e Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 21 May 2010 16:18:09 +0200 Subject: [PATCH] x86 platform drivers: hp-wmi Reorder event id processing Event id 0x4 defines the hotkey event. No need (or even wrong) to query HPWMI_HOTKEY_QUERY if event id is != 0x4. Reorder the eventcode conditionals and use switch case instead of if/else. Use an enum for the event ids cases.
