Subject: [ 66/77] ab8500_btemp: Demote initcall sequence
Date: Fri, 1 Mar 2013 11:44:51 -0800 [thread overview]
Message-ID: <20130301194358.950956129@linuxfoundation.org> (raw)
In-Reply-To: <20130301194351.913471337@linuxfoundation.org>
3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Rajanikanth H.V" <rajanikanth.hv@stericsson.com>
commit eeb0751c99522a4d1bbcc7b6bc1460cd07d07488 upstream.
Power supply subsystem creates thermal zone device for the property
'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready
before 'ab8500 battery temperature monitor' driver is initialized. ab8500
btemp driver is initialized with subsys_initcall whereas thermal subsystem
is initialized with fs_initcall which causes
thermal_zone_device_register(...) to crash since the required structure
'thermal_class' is not initialized yet:
