commit: 33a03aadb52fa05d28aba6d8f0c03c7b3b905897 [464/472] dcbnl: Prepare framework to shorten handling functions
config: x86_64-randconfig-net3 (attached as .config)

All related error/warning messages are:

net/dcb/dcbnl.c: In function ‘dcb_doit’:
include/net/netlink.h:497:41: warning: ‘reply_nlh’ may be used uninitialized in this function [-Wuninitialized]
net/dcb/dcbnl.c:1975:19: note: ‘reply_nlh’ was declared here


This is an auto and one-shot notification for new warnings.
It's perfectly fine to ignore it if the code is known good.
