zfs-dkms-git stopped working after upgrading my kernel to version 5.15.7. Unfortunately the patch which is included in the aur system does not work anymore due to a change in the original git repository. Thus a little tweak needs to be put in place to let the patch do its job.

The above code can replace the original aur patch and the package can be compiled with makepkg -si --skipchecksums
