From c9bcd582dfeec845b83bc948a430c9958bf839e6 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 27 Oct 2005 22:25:43 -0700 Subject: [PATCH] INPUT: Create symlinks for backwards compatibility This creates symlinks in /sys/class/input/ to the nested class devices to help userspace cope with the nesting. Unfortunatly udev still needs to be updated as it can't handle symlinks properly here :( Signed-off-by: Greg Kroah-Hartman --- drivers/input/evdev.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'drivers/input/evdev.c') diff --git a/drivers/input/evdev.c b/drivers/input/evdev.c index 2a96b260a2a..a4696cd0978 100644 --- a/drivers/input/evdev.c +++ b/drivers/input/evdev.c @@ -661,6 +661,7 @@ static struct file_operations evdev_fops = { static struct input_handle *evdev_connect(struct input_handler *handler, struct input_dev *dev, struct input_device_id *id) { struct evdev *evdev; + struct class_device *cdev; int minor; for (minor = 0; minor < EVDEV_MINORS && evdev_table[minor]; minor++); @@ -686,9 +687,13 @@ static struct input_handle *evdev_connect(struct input_handler *handler, struct evdev_table[minor] = evdev; - class_device_create(&input_class, &dev->cdev, + cdev = class_device_create(&input_class, &dev->cdev, MKDEV(INPUT_MAJOR, EVDEV_MINOR_BASE + minor), - dev->cdev.dev, "event%d", minor); + dev->cdev.dev, evdev->name); + + /* temporary symlink to keep userspace happy */ + sysfs_create_link(&input_class.subsys.kset.kobj, &cdev->kobj, + evdev->name); return &evdev->handle; } @@ -698,6 +703,7 @@ static void evdev_disconnect(struct input_handle *handle) struct evdev *evdev = handle->private; struct evdev_list *list; + sysfs_remove_link(&input_class.subsys.kset.kobj, evdev->name); class_device_destroy(&input_class, MKDEV(INPUT_MAJOR, EVDEV_MINOR_BASE + evdev->minor)); evdev->exist = 0; -- cgit v1.2.3
