    mtd: harmonize mtd_point interface implementation · 0dd5235f
    Artem Bityutskiy authored
    Some MTD drivers return -EINVAL if the 'phys' parameter is not NULL, trying to
    convey that they cannot return the physical address. However, this is not very
    logical because they still can return the virtual address ('virt'). But some
    drivers (lpddr) just ignore the 'phys' parameter instead, which is a more
    logical thing to do.
    Let's harmonize this and:
    1. Always initialize 'virt' and 'phys' to 'NULL' in 'mtd_point()'.
    2. Do not return an error if the physical address cannot be found.
    So as a result, all drivers will set 'phys' to 'NULL' if it is not supported.
    None of the 'mtd_point()' users use 'phys' anyway, so this should not break
    anything. I guess we could also just delete this parameter later.
