Bug#686152: xorg server 1.12.3: xf86UnloadSubModule() hangs, patch proposal

[Stephan Schreiber <info@fs-driver.org>]

I took a look at the most recent code in xorg's git repository  
(http://cgit.freedesktop.org/xorg/xserver/tree/).
All the functions which has been considered in this bug report do not  
differ from the ones of xorg-server 1.12.3:
hw/xfree86/common/xf86Helper.c: xf86UnloadSubModule()
hw/xfree86/loader/loadmod.c: UnloadModuleOrDriver(),  
UnloadSubModule(), RemoveChild(ModuleDescPtr()
with one exception that isn't relevant for our issue -  
UnloadModuleOrDriver() of 1.13 uses another function for log messages  
than 1.12.3.


I assume that the issue is also present on xorg-server 1.13.


Kind regards
Stephan Schreiber
