From: Alexander Sverdlin <[email protected]> of/spi: Honour "status=disabled" property of device
Currently of_register_spi_devices() function registers all SPI devices, independetly from their status property in device tree. According to "ePAPR 1.1" spec, device should only be registered if there is no "status" property, or it has "ok" (or "okay") value (see of_device_is_available()). In case of "platform devices", of_platform_device_create_pdata() checks for "status" and ensures that disabled devices are not pupulated. But such check for SPI buses was missing until now. Fix it.
