Subject: batman-adv: don't use !! in bool conversion
X-Git-Tag: firefly_0821_release~3680^2~548^2~457^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c1d07431b9f7fe3c5eb372f3a35d7cd7a18c3b15;p=firefly-linux-kernel-4.4.55.git

batman-adv: don't use !! in bool conversion

In C standard any expression different from 0 will be converted to
'true' when casting to bool (whatever is the length of the value).
Therefore all the "!!" conversions can be removed.
