From 5da50988a1bf8c05611db77521777baaca14da29 Mon Sep 17 00:00:00 2001 From: Nikolaus Voss Date: Wed, 9 May 2012 08:30:44 +0200 Subject: [PATCH] sbs-battery: Don't trigger false supply_changed event power_supply_changed() events are triggerd based on the return value of a get_property() call. However the property TECHNOLOGY is hard-coded to LION in this driver, thus always succeeds. So, with the battery removed, this triggers a false battery present uevent. This uevent triggers a new query via power_supply_uevent() which again starts to query all known properties and thus leads to an infinite loop of battery present/not-present uevents. This patch skips the battery presence detection for the hard-coded property TECHNOLOGY.
