usb_device is parent device of usb_interface in the view of driver model, so its reference count is always held during .probe/.disconnect of usb_interface instance. This patch just removes the unnecessay usb_get/put_dev. Signed-off-by: Ming Lei <redacted> --- drivers/net/usb/pegasus.c | 4 ---- 1 file changed, 4 deletions(-)
