Dear Maintainer,

Here is the summary:

   * What led up to the situation?
         I don't know when this problem first appeared as I was upgrading
regularly and did not need to remove the module. Recently I was forced to do a
fresh install and I needed to find out the card and tuner for the saa7134
module because the i2c system would not detect the correct card. To try
different settings I needed to unload and reload the saa7134 module multiple
times. But failed at the first attempt due to saa7134_alsa module being
reported as in use. Although lsmod says:
Module                  Size  Used by
saa7134_alsa           17686  0

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        rmmod -f saa7134_alsa
        modprobe -vfr saa7134_alsa

   * What was the outcome of this action?
        modprobe reported this error:
            modprobe: FATAL: Module saa7134_alsa is in use.
            modprobe: ERROR: ../libkmod/libkmod-module.c:777
kmod_module_remove_module() could not remove 'saa7134_alsa': Device or resource
busy

   * What outcome did you expect instead?
        removal of the module even without the "force" option, as was the case
in prior kernels.
