If a driver detects during - probing a device that a related device is not yet - ready, it may defer probing of the first device. The - kernel will retry probing the first device after any - other device is successfully probed. This attribute - reads as 1 if probing of this device is currently - deferred, or 0 otherwise. diff --git a/drivers/base/base.h b/drivers/base/base.h index ada9dce34e6d..e19b1008e5fb 100644 --- a/drivers/base/base.h +++ b/drivers/base/base.h @@ -141,8 +141,6 @@ extern void device_unblock_probing(void); extern struct kset *devices_kset; extern void devices_kset_move_last(struct device *dev); -extern struct device_attribute dev_attr_deferred_probe; - #if defined(CONFIG_MODULES) && defined(CONFIG_SYSFS) extern void module_add_driver(struct module *mod, struct device_driver *drv); extern void module_remove_driver(struct device_driver *drv); diff --git a/drivers/base/core.c b/drivers/base/core.c index 020ea7f05520..8c25e68e67d7 100644 --- a/drivers/base/core.c +++ b/drivers/base/core.c @@ -1060,14 +1060,8 @@ static int device_add_attrs(struct device *dev) goto err_remove_dev_groups; } - error = device_create_file(dev, &dev_attr_deferred_probe); - if (error) - goto err_remove_online; - return 0; - err_remove_online: - device_remove_file(dev, &dev_attr_online); err_remove_dev_groups: device_remove_groups(dev, dev->groups); err_remove_type_groups: @@ -1085,7 +1079,6 @@ static void device_remove_attrs(struct device *dev) struct class *class = dev->class; const struct device_type *type = dev->type; - device_remove_file(dev, &dev_attr_deferred_probe); device_remove_file(dev, &dev_attr_online); device_remove_groups(dev, dev->groups); diff --git a/drivers/base/dd.c b/drivers/base/dd.c index a8b258e5407b..a1fbf55c4d3a 100644 --- a/drivers/base/dd.c +++ b/drivers/base/dd.c @@ -53,19 +53,6 @@ static LIST_HEAD(deferred_probe_pending_list); static LIST_HEAD(deferred_probe_active_list); static atomic_t deferred_trigger_count = ATOMIC_INIT(0); -static ssize_t deferred_probe_show(struct device *dev, - struct device_attribute *attr, char *buf) -{ - bool value; - - mutex_lock(&deferred_probe_mutex); - value = !list_empty(&dev->p->deferred_probe); - mutex_unlock(&deferred_probe_mutex); - - return sprintf(buf, "%d\n", value); -} -DEVICE_ATTR_RO(deferred_probe); - /* * In some cases, like suspend to RAM or hibernation, It might be reasonable * to prohibit probing of devices as it could be unsafe. |
