Comment 53 for bug 246141

Here is source code which can compile without errors.
but when trying to insert module into kernel there's the error :

FATAL: Error inserting r8180 (/lib/modules/2.6.27-3-generic/kernel/drivers/net/wireless/r8180.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and dmesg says :
