From: "Matwey V. Kornilov" <matwey@xxxxxxxxxx>
This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit a43f32d647273023edddb0dc8f91c4c6378b252b ]
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.
