Subject: [PATCH] staging: android: ion_test: fix check of
platform_device_register_simple() error code
commit ccbc2a9e7878ff09bcaed4893c2a2d3adbb797e2 upstream.
On error platform_device_register_simple() returns ERR_PTR() value,
check for NULL always fails. The change corrects the check itself and
propagates the returned error upwards.
Fixes: 81fb0b901397 ("staging: android: ion_test: unregister the platform device")
