+ * At the beginning of a set request, uvc_ctrl_begin should be called to
+ * initialize the request. This function acquires the control lock.
+ *
+ * When setting a control, the new value is stored in the control data field

+ * value is loaded from the hardware before storing the new value in the data
+ * field.
+ *
+ * After processing all controls in the transaction, uvc_ctrl_commit or
+ * uvc_ctrl_rollback must be called to apply the pending changes to the
+ * hardware or revert them. When applying changes, all controls marked as
+ * dirty will be modified in the UVC device, and the dirty flag will be
+ * cleared. When reverting controls, the control data field
+ * UVC_CTRL_DATA_CURRENT is reverted to its previous value
+ * (UVC_CTRL_DATA_BACKUP) for all dirty controls. Both functions release the

+/* ------------------------------------------------------------------------
+ * Video buffers queue management.
+ *
+ * Video queues is initialized by uvc_queue_init(). The function performs
+ * basic initialization of the uvc_video_queue struct and never fails.
+ *
+ * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
+ * uvc_free_buffers respectively. The former acquires the video queue lock,
+ * while the later must be called with the lock held (so that allocation can
+ * free previously allocated buffers). Trying to free buffers that are mapped
+ * to user space will return -EBUSY.
+ *
+ * Video buffers are managed using two queues. However, unlike most USB video
+ * drivers which use an in queue and an out queue, we use a main queue which
+ * holds all queued buffers (both 'empty' and 'done' buffers), and an irq
+ * queue which holds empty buffers. This design (copied from video-buf)
+ * minimizes locking in interrupt, as only one queue is shared between
+ * interrupt and user contexts.
+ *
+ * Use cases
+ * ---------
+ *
+ * Unless stated otherwise, all operations which modify the irq buffers queue
+ * are protected by the irq spinlock.
+ *
+ * 1. The user queues the buffers, starts streaming and dequeues a buffer.
+ *
+ *    The buffers are added to the main and irq queues. Both operations are
+ *    protected by the queue lock, and the latert is protected by the irq
+ *    spinlock as well.
+ *
+ *    The completion handler fetches a buffer from the irq queue and fills it
+ *    with video data. If no buffer is available (irq queue empty), the handler
+ *    returns immediately.
+ *
+ *    When the buffer is full, the completion handler removes it from the irq
+ *    queue, marks it as ready (UVC_BUF_STATE_DONE) and wake its wait queue.
+ *    At that point, any process waiting on the buffer will be woken up. If a
+ *    process tries to dequeue a buffer after it has been marked ready, the
+ *    dequeing will succeed immediately.
+ *
+ * 2. Buffers are queued, user is waiting on a buffer and the device gets
+ *    disconnected.
+ *
+ *    When the device is disconnected, the kernel calls the completion handler
+ *    with an appropriate status code. The handler marks all buffers in the
+ *    irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
+ *    that any process waiting on a buffer gets woken up.
+ *
+ *    Waking up up the first buffer on the irq list is not enough, as the
+ *    process waiting on the buffer might restart the dequeue operation
+ *    immediately.

+ * Privilege management is the multiple-open implementation basis. The current
+ * implementation is completely transparent for the end-user and doesn't
+ * require explicit use of the VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY ioctls.
+ * Those ioctls enable finer control on the device (by making possible for a
+ * user to request exclusive access to a device), but are not mature yet.
+ * Switching to the V4L2 priority mechanism might be considered in the future
+ * if this situation changes.
+ *
+ * Each open instance of a UVC device can either be in a privileged or
+ * unprivileged state. Only a single instance can be in a privileged state at
+ * a given time. Trying to perform an operation which requires privileges will
+ * automatically acquire the required privileges if possible, or return -EBUSY
+ * otherwise. Privileges are dismissed when closing the instance.
+ *
+ * Operations which require privileges are:
+ *
+ * - VIDIOC_S_INPUT
+ * - VIDIOC_S_PARM
+ * - VIDIOC_S_FMT
+ * - VIDIOC_TRY_FMT
+ * - VIDIOC_REQBUFS
