Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux 

Pull thermal management fixes from Zhang Rui.

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  thermal: exynos_thermal: return a proper error code while thermal_zone_device_register fail.
  thermal: rcar_thermal: propagate return value of thermal_zone_device_register
  Thermal: kirkwood: Convert to devm_ioremap_resource()
  Thermal: rcar: Convert to devm_ioremap_resource()
  Thermal: dove: Convert to devm_ioremap_resource()
  thermal: rcar: fix missing unlock on error in rcar_thermal_update_temp()
