3.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Matwey V. Kornilov" <matwey@xxxxxxxxxx>
commit a43f32d647273023edddb0dc8f91c4c6378b252b upstream.
Struct spear13xx_pcie_driver was in initdata, but we passed a pointer to it
to platform_driver_register(), which can use the pointer at arbitrary times
in the future, even after the initdata is freed. That leads to crashes.
Move spear13xx_pcie_driver and things referenced by it
(spear13xx_pcie_probe() and dw_pcie_host_init()) out of initdata.
[bhelgaas: changelog]
Fixes: 6675ef212dac ("PCI: spear: Fix Section mismatch compilation warning for probe()")
