Ah, this patch is juste a cleanup. It replaces your patch 2.

The idea was that, after this cleanup, you'd adapt your patch 1 n top of
it, with something like:

    diff --git a/package/linux-firmware/linux-firmware.mk b/package/linux-firmware/linux-firmware.mk
    index 9bc59435ef..8defedd309 100644
    --- a/package/linux-firmware/linux-firmware.mk
    +++ b/package/linux-firmware/linux-firmware.mk

And then your patch 3 look like:

    diff --git a/package/linux-firmware/linux-firmware.mk b/package/linux-firmware/linux-firmware.mk
    index 9bc59435ef..8defedd309 100644

And then your final patch 4.
