The patch titled
Subject: drivers/thermal/spear_thermal.c: add Device Tree probing capability
has been removed from the -mm tree. Its filename was
drivers-thermal-spear_thermalc-add-device-tree-probing-capability.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

From: Viresh Kumar <viresh.linux@xxxxxxxxx>
Subject: drivers/thermal/spear_thermal.c: add Device Tree probing capability
SPEAr platforms now support DT and so must convert all drivers to support
DT. This patch adds DT probing support for SPEAr thermal sensor driver
and updates its documentation too.
Also, as SPEAr is the only user of this driver and is only available with
DT, make this an only DT driver. So, platform_data is completely removed
and passed via DT now.
