DKMS 2.8.4 version is broken

Describe the bug

When we try

sudo dkms install jool/4.1.5.git.v4.1.5.16.g88339465 and sudo dkms uninstall jool/4.1.5.git.v4.1.5.16.g88339465,
the commands silently succeeding without installing kernel modules(.ko files).

Reproduction steps

1. Install jool

My node shows:
zsh 1 % jool --version
4.1.5.3

2. sudo tdnf install dkms
Installing:
dkms noarch 2.8.2-2.ph4 photon-updates 194.54k 199214
Total installed size: 194.54k 199214
Is this ok [y/N]: y
Downloading:
dkms 67029 100%
Testing transaction
Running transaction
Installing/Updating: dkms-2.8.2-2.ph4.noarch
Complete!


3. dkms --version
dkms:2.8

4. 
<vmware@dev:> % sudo dkms install jool/4.1.5.git.v4.1.5.16.g88339465. ----> Not installed anything
[Thu 22/01/13 21:56 UTC][pts/35][x86_64/linux-gnu/5.10.78-4.ph4-esx][5.8]


5. Silently succeeded and didn't generate KO modules for jool.

zsh 27 % cd /lib/modules/5.10.78-4.ph4-esx/extra/
[Tue 22/01/18 16:00 UTC][pts/35][x86_64/linux-gnu/5.10.78-4.ph4-esx][5.8]
<vmware@dev:/lib/modules/5.10.78-4.ph4-esx/extra>
zsh 28 % ls
i40e.ko.xz  iavf.ko.xz  ice.ko.xz

Expected behavior

It should generate KO modules(ool_common.ko.xz jool.ko.xz jool_siit.ko.xz)for Jool.

Have tried with latest version from "https://github.com/dell/dkms" which is v3.0.3

1.git clone https://github.com/dell/dkms

2.cd dkms

3. zsh 34 (git)-[master]-% sudo make install

   mkdir -p /var/lib/dkms

   install -D -m 0755 kernel_prerm.d_dkms /etc/kernel/prerm.d/dkms
   gzip -9 /usr/share/man/man8/dkms.8
   gzip: /usr/share/man/man8/dkms.8.gz already exists; do you wish to overwrite (y or n)? y

4. zsh 4 (git)-[master]-% dkms --version
   dkms-3.0.3

Additional context

Please update DKMS version from v2.8.4 to v3.0.3

Start by reproducing the DKMS 2.8.4 behavior with the listed tdnf and dkms commands on the Photon kernel, then compare it with the demonstrated DKMS 3.0.3 installation. Trace how the Photon package supplies DKMS and verify that installing Jool produces jool_common.ko.xz, jool.ko.xz, and jool_siit.ko.xz in the kernel's extra directory.
