[cip-dev] [PATCH] spi: pxa2xx-pci: fix ACPI-based enumeration of SPI devices

[Jan Kiszka]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

commit b70cd2de0ea85f5ab51a1d01893cba6415011b9d upstream.

Slave devices are not enumerated by ACPI data because the ACPI handle for the
core driver is NULL if it was enumerated by PCI.

Propagate firmware node handle of the PCI device to the platform device.

Required for our IOT2000 devices to work properly.
