Subject: PCI: spear: Drop __initdata from spear13xx_pcie_driver
From: "Matwey V. Kornilov" <[email protected]>
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.
