Hi Luis
 
    I am porting the compat-wireless-2.6.32-3 to my powerpc platform
with 2.6.25 kernel.  After disable the LED marco in config.mk i have
compile it sucess. but when i load it , it show below error messages,
anyone can help on this?
the kernel modules manually load order is below: am i right ?
    1. rfkill_backport
     2. cfg_802.11
     3. mac80211
         4. ath
         5. ath9k
#insmod rfkill_backport.ko 
rfkill_backport: Unknown symbol dev_set_name
insmod: cannot insert 'rfkill_backport.ko': unknown symbol in module
(-1): No such file or directory
 
 i found that the compat-2.6.26 have the dev_set_name function, but
compat-2.6.25 don't have this. 
  In new kernel(2.6.29)  it's is device/base/core.c, then i try to copy
the function into my 2.6.25 kernel.
but it loss the 'kobject_set_name_vargs', here is the compile
information.
$drivers/base/core.c: In function 'dev_set_name':
$drivers/base/core.c:880: error: implicit declaration of function
'kobject_set_name_vargs'
 
Regards
Yanfei
