From 9caf26360367a8b28ca7c6961887052509d61fbd Mon Sep 17 00:00:00 2001
From: Peter Hutterer <peter.hutterer@who-t.net>

Subject: Allow building the driver without serial ISDV4 support

If configured with -Disdv4=false, the ISDV4 serial
bits will not be built, including the udev rules and the inputattach
helper and service files.

This is meson only.
