Patch first, then install driver, then install the linux agent. Exactly like this:

cd /tmp
tar zxvf VMware-horizonagent-linux-x86_64-2111.1-8.4.0-19155374.tar.gz

apt-get install make gcc libelf-dev
download the 1.15 zip https://sourceforge.net/projects/usb-vhci/files/linux%20kernel%20module/
tar xzvf vhci-hcd-1.15.tar.gz
cd vhci-hcd-1.15
patch -p1 < /tmp/VMware-horizonagent-linux-x86_64-2111.1-8.4.0-19155374/resources/vhci/patch/vhci.patch
make clean && make && make install

cd /tmp/VMware-horizonagent-linux-x86_64-2111.1-8.4.0-19155374
./install_viewagent.sh -A yes -U yes
