The rpi firmware short log looks like:

10c1c5f963 kernel: Bump to 4.14.76
fbad6408c4 kernel: Bump to 4.14.74
e924d3e880 kernel: Bump to 4.14.73
e80b826911 kernel: Bump to 4.14.72

Not very informative, the long log looks like:

    kernel: Bump to 4.14.76
    kernel: Revert net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends
    See: https://github.com/raspberrypi/linux/pull/2717
    kernel: thermal: add hysteresis support and adjust PoE HAT trip points
    See: https://github.com/raspberrypi/linux/pull/2700
    kernel: Add composite RPi driver for pcm512x DAC HAT cards
    See: https://github.com/raspberrypi/linux/pull/2702
    firmware: jpeg/mjpeg: MJPEG doesn't insert JFIF APP0 header
    See: https://github.com/raspberrypi/userland/issues/345
    firmware: Add IL HVS component
    firmware: mmal: Acquire zero copy buffers on being passed to the VPU
    firmware: video_render: Use per pixel alpha on RGBA and BGRA
    firmware: video_render: Add support for alpha options (MIX and PREMULT)

Hard to judge what is needed, what is a feature update, what is a security update
and should applied to the long term support buildroot branches....

One solution would be (as long as the rpi kernel updates keep the same major/minor version),
to say this are security updates (as the mainline kernel updates) and try to keep
rpi-userland and rpi-firmware at the same commit level (I can add the referenced kernel version
to the commit log)....

The other solution would be not to backport the rpi updates at all?
