Pull thermal management fixes from Eduardo Valentin:
 "Specifics:

   - adding Lukasz as maintainer of samsung thermal driver.
   - driver fixes: exynos and int430x.
   - one fix in the exynos cpufreq driver related to cpu cooling (acked
     by cpufreq maintainer).
   - fix default sysfs attributes of cooling devices

  Note: I am sending this pull on Rui's behalf while he fixes issues in his Linux box"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal:
  thermal: Make sysfs attributes of cooling devices default attributes
  Thermal/int340x: Fix memleak for aux trip
  MAINTAINERS: Add entry for SAMSUNG THERMAL DRIVER
  cpufreq: exynos: Use simple approach to asses if cpu cooling can be used
  thermal: exynos: Fix wrong control of power down detection mode for Exynos7
