[PATCH] Input: sun4i-ts: add thermal driver dependency

[PATCH] Input: sun4i-ts: add thermal driver dependency

[Arnd Bergmann]

The sun4i-ts driver has had a dependency on the thermal code
since it was first merged, but this is not currently enforced
in Kconfig, so in some randconfig builds we get

drivers/built-in.o: In function `sun4i_ts_remove':
:(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister'
drivers/built-in.o: In function `sun4i_ts_probe':
:(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register'
:(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'

We need the dependency on THERMAL in order to ensure that this
driver becomes a loadable module if the thermal support itself
is modular, while the dependency on THERMAL_OF is a runtime dependency
and the driver will still build but not work if it is missing.

The "since it was first merged bit" is not true, this is caused
by recent changes by ChenYu.

Other then that no objections from me against the proposed fix.

THERMAL_OF does have proper stubs and I do not see why we need to force
having TERMAL even if we don't do compile test. Should the dependency be:

	depends on !THERMAL_OF || TERMAL

Thanks.

ChenYu, since your patch causes this problem I'm assuming that you will come
up with a fix, is that correct ?

                                    ^^^ typo

Yes this solves the problem.
