Clippy warns about a reimplementation of `RangeInclusive::contains`:

    error: manual `!RangeInclusive::contains` implementation
       --> drivers/gpu/drm/drm_panic_qr.rs:986:8
        |
    986 |     if version < 1 || version > 40 {
        |        ^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use: `!(1..=40).contains(&version)`
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#manual_range_contains
        = note: `-D clippy::manual-range-contains` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::manual_range_contains)]`

Ignore this and keep the current implementation as that makes it easier
to read.
