I've applied after doing a few tweaks, see below.

I've completely dropped this option. Indeed, it is already possible
without your patch to select a custom Git repository to download the
kernel. So having yet another option to do that is useless. If you want
to use a custom CIP repository, just use the existing
BR2_LINUX_KERNEL_CUSTOM_GIT option.

Since this help text was useful, I've moved it under the
BR2_LINUX_KERNEL_LATEST_CIP_VERSION option.

This prompt was too long and didn't fit in the menuconfig window. So
I've removed the "(Super Long Term Support)" part of it, which is
anyway explained in the help text.

Applied with those two changes. Thanks!
