[ Upstream commit b049e7abe9001a780d58e78e3833dcceee22f396 ]
struct platform_device::id was only set by board code, but since i.MX became a devicetree-only platform, this will always be -1 (PLATFORM_DEVID_NONE).
Note: of_alias_get_id() returns a negative number on error and base treats all negative errors the same, so we need not add any additional error handling.
