From 82b1698314f004b9d69a14c5054e5f7699aa33ad Mon Sep 17 00:00:00 2001 From: "kay.sievers@vrfy.org" Date: Fri, 11 Feb 2005 05:21:03 +0100 Subject: [PATCH] namedev: if SUBSYSTEM or KERNEL key doesn't match, give up immediately We don't need to look at the parents in the device chain. There will never be another kernel name or subsystem. --- namedev.c | 48 ++++++++++++++++++++++++------------------------ 1 file changed, 24 insertions(+), 24 deletions(-) diff --git a/namedev.c b/namedev.c index 90d988311e..bbc5b40069 100644 --- a/namedev.c +++ b/namedev.c @@ -583,32 +583,15 @@ static int match_rule(struct udevice *udev, struct config_device *dev, struct sysfs_class_device *class_dev, struct sysfs_device *sysfs_device) { while (1) { - /* check for matching bus value */ - if (dev->bus[0] != '\0') { - if (sysfs_device == NULL) { - dbg("device has no bus"); - goto try_parent; - } - dbg("check for " FIELD_BUS " dev->bus='%s' sysfs_device->bus='%s'", - dev->bus, sysfs_device->bus); - if (strcmp_pattern(dev->bus, sysfs_device->bus) != 0) { - dbg(FIELD_BUS " is not matching"); - goto try_parent; - } else { - dbg(FIELD_BUS " matches"); - } - } - /* check for matching kernel name */ if (dev->kernel[0] != '\0') { dbg("check for " FIELD_KERNEL " dev->kernel='%s' class_dev->name='%s'", dev->kernel, class_dev->name); if (strcmp_pattern(dev->kernel, class_dev->name) != 0) { dbg(FIELD_KERNEL " is not matching"); - goto try_parent; - } else { - dbg(FIELD_KERNEL " matches"); + goto exit; } + dbg(FIELD_KERNEL " matches"); } /* check for matching subsystem */ @@ -617,10 +600,9 @@ static int match_rule(struct udevice *udev, struct config_device *dev, dev->subsystem, class_dev->name); if (strcmp_pattern(dev->subsystem, udev->subsystem) != 0) { dbg(FIELD_SUBSYSTEM " is not matching"); - goto try_parent; - } else { - dbg(FIELD_SUBSYSTEM " matches"); + goto exit; } + dbg(FIELD_SUBSYSTEM " matches"); } /* check for matching driver */ @@ -635,6 +617,21 @@ static int match_rule(struct udevice *udev, struct config_device *dev, } } + /* check for matching bus value */ + if (dev->bus[0] != '\0') { + if (sysfs_device == NULL) { + dbg("device has no bus"); + goto try_parent; + } + dbg("check for " FIELD_BUS " dev->bus='%s' sysfs_device->bus='%s'", + dev->bus, sysfs_device->bus); + if (strcmp_pattern(dev->bus, sysfs_device->bus) != 0) { + dbg(FIELD_BUS " is not matching"); + goto try_parent; + } + dbg(FIELD_BUS " matches"); + } + /* check for matching bus id */ if (dev->id[0] != '\0') { dbg("check " FIELD_ID); @@ -695,17 +692,20 @@ static int match_rule(struct udevice *udev, struct config_device *dev, } } - /* Yeah, we matched! */ + /* we matched */ return 0; try_parent: dbg("try parent sysfs device"); sysfs_device = sysfs_get_device_parent(sysfs_device); if (sysfs_device == NULL) - return -ENODEV; + goto exit; dbg("sysfs_device->path='%s'", sysfs_device->path); dbg("sysfs_device->bus_id='%s'", sysfs_device->bus_id); } + +exit: + return -1; } int namedev_name_device(struct udevice *udev, struct sysfs_class_device *class_dev) -- cgit v1.2.3-54-g00ecf
