Krzysztof Kozlowski 2ea8bab4dd iio: adc: exynos-adc: Fix NULL pointer exception on unbind 
Fix NULL pointer exception on device unbind when device tree does not
contain "has-touchscreen" property.  In such case the input device is
not registered so it should not be unregistered.

    $ echo "12d10000.adc" > /sys/bus/platform/drivers/exynos-adc/unbind

    Unable to handle kernel NULL pointer dereference at virtual address 00000474
