    Merge branch 'bpf-add-missing-precision-propagation-after-bpf_register_is_null-calls'

    Eduard Zingerman says:

    ====================
    bpf: add missing precision propagation after bpf_register_is_null calls

    Fix [1] uncovered a host of locations where the call to
    bpf_register_is_null() is not followed by a call to
    bpf_mark_chain_precision().

    check_map_kptr_access() is omitted as it is handled [2]
    by another series.
