X-Git-Tag: firefly_0821_release~12983^2~288 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0d788c7d285a91ef72a7b436dbe753d117856b3d;p=firefly-linux-kernel-4.4.55.git qeth: display service_level info only when valid. qeth displayed an entry in /proc/service_level even when no valid MCL-string was available (the MCL info is blank). The change is to create an entry in /proc/service_level only when MCL-string is non-zero. Signed-off-by: Klaus-Dieter Wacker Signed-off-by: David S.
