Staging: rtl8192u: Remove unnecessary variable
This patch detects the cases in which a variable is not modified through the code and it is used as a return value. The variable is detected and removed by coccinelle using the following semantic patch: @@ type T; expression expr; identifier r; constant c; @@ -T r = expr; ... when != r when strict -return r; +return expr; Signed-off-by: Cristina Opriceana <cristina.opriceana@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
