63acb87329 modem.conf Off-hook improve behavior 
Only restore the old value if it differs from the requested
value, because if it has changed restoring the old value
overrides the change.  Take for example, a voice modem with
a .conf that sets preserve off-hook.  Start playback (on-hook
to off-hook), start record (off-hook to off-hook), stop
playback (off-hook to restore on-hook), stop record (on-hook
to restore off-hook), Clearly you don't want to leave the
modem "on the phone" now that there isn't any playback or
recording active.

d5caee8d36 Fix bogus value when no user TLV is defined 
Check whether non-zero size TLV is really returned by comparing
with the pre-filled pattern.  ALSA 1.0.12 driver doesn't notify
the error even if user TLV is empty, so the previous value is
passed bogusly.
