From dc4ebc0787a299f064553e6d28a7f35574ce1c2a Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 17 Aug 2015 09:30:49 +0200 Subject: Bug #944: Deletion of unnecessary checks before calls of the function "free" The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.1. --- src/udev/udev-builtin-path_id.c | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) (limited to 'src/udev') diff --git a/src/udev/udev-builtin-path_id.c b/src/udev/udev-builtin-path_id.c index aa5cda6fe7..f529ffcf25 100644 --- a/src/udev/udev-builtin-path_id.c +++ b/src/udev/udev-builtin-path_id.c @@ -117,8 +117,7 @@ static struct udev_device *handle_scsi_fibre_channel(struct udev_device *parent, format_lun_number(parent, &lun); path_prepend(path, "fc-%s-%s", port, lun); - if (lun) - free(lun); + free(lun); out: udev_device_unref(fcdev); return parent; @@ -156,8 +155,7 @@ static struct udev_device *handle_scsi_sas_wide_port(struct udev_device *parent, format_lun_number(parent, &lun); path_prepend(path, "sas-%s-%s", sas_address, lun); - if (lun) - free(lun); + free(lun); out: udev_device_unref(sasdev); return parent; @@ -251,8 +249,7 @@ static struct udev_device *handle_scsi_sas(struct udev_device *parent, char **pa else path_prepend(path, "sas-phy%s-%s", phy_id, lun); - if (lun) - free(lun); + free(lun); out: udev_device_unref(target_sasdev); udev_device_unref(expander_sasdev); @@ -313,8 +310,7 @@ static struct udev_device *handle_scsi_iscsi(struct udev_device *parent, char ** format_lun_number(parent, &lun); path_prepend(path, "ip-%s:%s-iscsi-%s-%s", addr, port, target, lun); - if (lun) - free(lun); + free(lun); out: udev_device_unref(sessiondev); udev_device_unref(conndev); -- cgit v1.2.3-54-g00ecf
