This patch compresses two lines into a single line if immediate return is found. Variable rc is dropped as it is no longer needed.
Semantic patch used for this is as follows: @@ 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 <shraddha.6...@gmail.com> --- drivers/staging/dgnc/dgnc_neo.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/drivers/staging/dgnc/dgnc_neo.c b/drivers/staging/dgnc/dgnc_neo.c index 900e3ae..321783c 100644 --- a/drivers/staging/dgnc/dgnc_neo.c +++ b/drivers/staging/dgnc/dgnc_neo.c @@ -1316,7 +1316,6 @@ static int neo_drain(struct tty_struct *tty, uint seconds) unsigned long flags; struct channel_t *ch; struct un_t *un; - int rc = 0; if (!tty || tty->magic != TTY_MAGIC) return -ENXIO; @@ -1339,10 +1338,7 @@ static int neo_drain(struct tty_struct *tty, uint seconds) * * NOTE: TODO: Do something with time passed in. */ - rc = wait_event_interruptible(un->un_flags_wait, ((un->un_flags & UN_EMPTY) == 0)); - - /* If ret is non-zero, user ctrl-c'ed us */ - return rc; + return wait_event_interruptible(un->un_flags_wait, ((un->un_flags & UN_EMPTY) == 0)); } -- 2.1.0 _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
