[LTP] [PATCH] CI: do not checkout submodules

[Petr Vorel]

Hi Cyril,

> This was originally added so that kirk installation is tested. The
> problem is that this brings random failures when git.kernel.org timeouts
> when we are checking out submodules that are not needed for the build
> and neither for the installation.

> Unfortunatelly there is no support for selective submodule installation
> in github checkout action. There is an issue and pull request hanging:

> https://github.com/actions/checkout/pull/1866
> https://github.com/actions/checkout/issues/1969

> It looks like if we wanted to checkout only kirk submodule we would have
> to install git and run all the commands ourselves in the CI, which I
> would like to avoid. Hence this commit removes the submodules checkout
> from the CI, with that we sacrifice kirk installation testing but avoid
> random failures.

I'm ok with it.
nit: I'd mention it is actually a revert of 9cde2740cc.
