Git clone failure

[vrrdd]

Ubuntu 20.04.6 LTS
5.15.0-124-generic x86_64 HWE kernel

Cloning fails with the following error:

~/alx_dkms_installer$ ./setup
Checking dependencies...
Done
Downloading kernel source for 5.15.0 by git...
Cloning into 'linux-5.15.0'...
warning: Could not find remote branch 5.15.y to clone.
fatal: Remote branch 5.15.y not found in upstream origin
git failed to download the source. Check the output for information.

Based on git clone arguments, I suspect there has been a recent(?) naming change in linux source tree and/or its branches.

~/alx_dkms_installer$ diff setup setup_fix
18c18
<     git clone --depth 1 -b "v$kv" git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git "linux-$kv"
---
>     git clone --depth 1 -b "linux-${kv%?}y" https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git "linux-$kv"

Above change seems to fix the script, at least on the aforementioned machine.
