Subject: staging: rtl8188eu: rewrite the right hand side of an assignment
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=10a8643b766b10230e9f795d6c1ac716ee03b40c;p=openwrt%2Fstaging%2Fblogic.git

staging: rtl8188eu: rewrite the right hand side of an assignment

This patch rewrites the right hand side of an assignment for
expressions of the form:
a = (a <op> b);
to be:
a <op>= b;
where <op> = << | >>.

This issue was detected and resolved using the following
coccinelle script:

@@
identifier i;
expression e;
@@

-i = (i >> e);
+i >>= e;

@@
identifier i;
expression e;
@@

-i = (i << e);
+i <<= e;
