Subject: Patch from Egor Duda Attached patch prevents modprobe from trying to
 call 'insmod (null)' whenever nonexistent module is either passed to modprobe
 via command line or mentioned in modules.dep

this replaces cryptic error
sh: Syntax error: word unexpected (expecting ")")
with
modprobe: module some-module not found.

egor.
