# HG changeset patch # User Janne Grunau <j@xxxxxxxxxx> # Date 1238189646 -3600 # Node ID 602a8fff1ba466ec4fb4816d0fb0725c8650c311 # Parent b1596c6517c925abd1e683e86592af1aedf9de06 v4l: use usb_interface for v4l2_device_register From: Janne Grunau <j@xxxxxxxxxx> If usb_interface.dev is used as dev parameter for v4l2_device_register v4l2_dev.name contains the v4l driver/module name and usb device and interface instead of a simple "usb x-y". It also matches the recommendation to set the parent devices for usb drivers.

The first 'dev' argument is normally the struct device pointer of a pci_dev, -usb_device or platform_device. It is rare for dev to be NULL, but it happens +usb_interface or platform_device. It is rare for dev to be NULL, but it happens with ISA devices or when one device creates multiple PCI devices, thus making it impossible to associate v4l2_dev with a particular parent. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
