From 6ba4df24bb87246472be90b11fcecb720c2a15ba Mon Sep 17 00:00:00 2001 From: Shraddha Barke Date: Mon, 27 Jul 2015 23:30:52 +0530 Subject: [PATCH] Staging:dgap :Compression of lines for immediate return This patch compresses two lines into a single line if immediate return statement is found. Remove variable rc as it is no longer needed. It is done using script Coccinelle. And coccinelle uses the following semantic patch for this compression function: @@ type T; identifier i,f; constant C; @@ - T i; ...when != i when strict ( return -C; | - i = + return f(...); - return i; ) Signed-off-by: Shraddha Barke Signed-off-by: Greg Kroah-Hartman --- drivers/staging/dgap/dgap.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/staging/dgap/dgap.c b/drivers/staging/dgap/dgap.c index b344e035b0ef..9112dd2bf4d7 100644 --- a/drivers/staging/dgap/dgap.c +++ b/drivers/staging/dgap/dgap.c @@ -4953,9 +4953,8 @@ static int dgap_tty_ioctl(struct tty_struct *tty, unsigned int cmd, spin_unlock_irqrestore(&ch->ch_lock, lock_flags2); spin_unlock_irqrestore(&bd->bd_lock, lock_flags); - rc = put_user(C_CLOCAL(tty) ? 1 : 0, + return put_user(C_CLOCAL(tty) ? 1 : 0, (unsigned long __user *) arg); - return rc; case TIOCSSOFTCAR: spin_unlock_irqrestore(&ch->ch_lock, lock_flags2); -- 2.20.1
