    Subject[PATCH 64/69] Revert "net: liquidio: fix a NULL pointer dereference"
    Date
    This reverts commit fe543b2f174f34a7a751aa08b334fe6b105c4569.

    Because of recent interactions with developers from @umn.edu, all
    commits from them have been recently re-reviewed to ensure if they were
    correct or not.

    Upon review, this commit was found to be incorrect for the reasons
    below, so it must be reverted. It will be fixed up "correctly" in a
    later kernel change.

    While the original commit does keep the immediate "NULL dereference"
    from happening, it does not properly propagate the error back to the
    callers, AND it does not fix this same identical issue in the
    drivers/net/ethernet/cavium/liquidio/lio_vf_main.c for some reason.
