The commit below from 2005 (sic) seems to be an example that workarounds 
often have quite a long lifetime.

Can we get this sorted out properly for 2.6.22?


commit c7ac6b42ffba28c350cbcd48268f46689f6eb1cc
Author: Linus Torvalds <>
Date:   Wed Dec 21 14:52:32 2005 -0800

    Initialize drivers/media/video/saa7134 late
    When compiled-in, make sure the sound system has initialized
    before these drivers do.
    Reported by Adrian Bunk <>
    (The right fix would be to make the sound core use "subsys_initcall()"
    and thus initialize before all normal drivers, but this is the quick
    and limited safe fix for 2.6.15).
