Subject: [PATCH 3/3] thermal: allow u8500-thermal driver to be a module
Date: Mon, 25 Jan 2016 17:44:12 +0100	[thread overview]
Message-ID: <1453740264-1972562-4-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1453740264-1972562-1-git-send-email-arnd@arndb.de>

When the thermal subsystem is a loadable module, the u8500 driver
fails to build:

drivers/thermal/built-in.o: In function `db8500_thermal_probe':
db8500_thermal.c:(.text+0x96c): undefined reference to `thermal_zone_device_register'
drivers/thermal/built-in.o: In function `db8500_thermal_work':
db8500_thermal.c:(.text+0xab4): undefined reference to `thermal_zone_device_update'

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