- * This scheme has several advantages over older methods:
- *

- * CONTEXT_BITS bits of context for user addresses.
- * i.e. 64T (46 bits) of address space for up to half a million contexts.

- * - The scramble function gives robust scattering in the hash

* usb_composite_probe() - register a composite driver
* @driver: the driver to register
- * @bind: the callback used to allocate resources that are shared across the
- * whole device, such as string IDs, and add its configurations using
- * @usb_add_config(). This may fail by returning a negative errno
- * value; it should return zero on successful initialization.
+ *
* Context: single threaded during gadget setup
*
* This function is used to register drivers using the composite driver
