From 52a0ba82e1ad180f9f91920db70a758fac49466a Mon Sep 17 00:00:00 2001
From: Yauheni Kaliuta <yauheni.kaliuta@redhat.com>

Subject: [PATCH] modprobe: ignore builtin module on recursive removing
If there are built-in dependencies and any of them is built-in in
the kernel, modprobe -r fails with
modprobe: FATAL: Module module_name is builtin.
It makes sense to ignore such dependencies for the case when
removing is called for non-top level module.
Example: cifs module, it declares bunch of softdeps and the first
one fails on some kernel configs:
modprobe: FATAL: Module gcm is builtin.

# This is an updated version of the script which doesn't support
# multiple installation of the same out-of-tree module (stored in the
