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; Signed-off-by: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
