Subject: Staging: wlan-ng: Remove multiple assignments
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0c42bc25ed916d0fba1205cbdf668c38717fca77;p=openwrt%2Fstaging%2Fblogic.git

Staging: wlan-ng: Remove multiple assignments

Remove multiple assignments by factorizing them.
Made a coccinelle script to match cases:
@@
identifier a,b;
constant c;
@@
-a=b=c;
+a=c;
+b=c;
