staging: lustre: lustre: obdecho: expand the GOTO macro in echo_client.c
The GOTO macro is not standard in Linux. The following Coccinelle semantic patch was used to expand the GOTO macro. @@ identifier lbl; identifier rc; constant c; @@ - GOTO(lbl,\(rc\|c\)); + goto lbl; @@ identifier lbl; expression rc; @@ - GOTO(lbl,rc); + rc; + goto lbl; Signed-off-by: Jiayi Ye <yejiayily@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>hifive-unleashed-5.1
