[PATCH 4.4 034/114] thermal: allow spear-thermal driver to be a module

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 4d2f1794c07aae55b8f25f4d8aebcafc0d3e501d ]

When the thermal subsystem is a loadable module, the spear driver
fails to build:

drivers/thermal/built-in.o: In function `spear_thermal_exit':
spear_thermal.c:(.text+0xf8): undefined reference to `thermal_zone_device_unregister'
drivers/thermal/built-in.o: In function `spear_thermal_probe':
spear_thermal.c:(.text+0x230): undefined reference to `thermal_zone_device_register'

This changes the symbol to a tristate, so Kconfig can track the
dependency correctly.
