    omap: drop __initdata tags from static struct platform_device declarations · 07ad6ab3
    Janusz Krzysztofik authored
    Pointers to statically declared platform device structures which are
    registered with platform_device_register() are then used during run time
    to access these structure members, for example from platform_uevent()
    and much more. Therefore, these structures should never be placed inside
    sections which are dropped after boot. Fix platform devices incorrectly
    tagged with __initdata which happen to exist inside OMAP sub-trees.
    This bug has exhibited itself on my ARM/OMAP1 based Amstrad Delta
    videophone after commit 6d3163ce
    , "mm:
    check if any page in a pageblock is reserved before marking it
    MIGRATE_RESERVE", resulting in reading from several
    /sys/device/platform/*/uevent files always ending up with segmentation
