From 52fa74ee690e6491295ac221c83c56563257f294 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 24 Feb 2015 10:54:46 +0100 Subject: [PATCH] power_supply: max17040: Use system efficient workqueues The scheduled work in max17040_battery driver reads device parameters and stores them in memory. Any CPU could do that so use system efficient workqueues to limit unnecessary CPU wake ups.
