This properly ties the driver into the dynamic debug system and provides
the needed device identification when the messages are printed out.
It also removes a ton of checkpatch warnings as well, which is always a
nice validation that it's the correct thing to do.

This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.
Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt). If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.
The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.
A manage_power stub doing direct flag manipulation is used in normal
driver mode.

The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

is suspicious. ... In this particular case sizeof(struct

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.
Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
cp210x_port_private struct, and use the interface number there in the
usb_control_message wIndex param

USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
a patch making modules behave better, there's a fix on debugfs'
error path, a small change removing an unnecessary pm_runtime
call on musb_shutdown() and a fix to relesect the endpoint in
Interrupt context.
This last patch is needed because we must drop musb's lock when
calling request->complete() and that could cause problems if another
thread queues a request and ends up changing MUSB_INDEX register.

USB: MUSB changes for 3.4
Here are a set of changes to the MUSB driver. In summary we have
a patch making modules behave better, there's a fix on debugfs'
error path, a small change removing an unnecessary pm_runtime
call on musb_shutdown() and a fix to relesect the endpoint in
Interrupt context.
This last patch is needed because we must drop musb's lock when
calling request->complete() and that could cause problems if another
thread queues a request and ends up changing MUSB_INDEX register.
