22654b41a7 symbol: Remove various bits of left over junk
There are various bits of code here that are unfinished and instead of
being harmless either confuse or spew stuff into the logs at higher than
debug level. They can and should go away.

Also remove the bogus use of tty->lowlatency. We fixed the need for this hack
long ago (with the flip buffer rewrite) but people keep copying it into drivers.

e766aeb882 usb: Auto-load cdc_acm module when device opened.
The cdc_acm module is missing the char-major-166-* alias that would
cause it to be auto-loaded when a device of that type is opened.  This
patch adds the alias.

bf6aede712 workqueue: add to_delayed_work() helper function
It is a fairly common operation to have a pointer to a work and to need a
pointer to the delayed work it is contained in.  In particular, all
delayed works which want to rearm themselves will have to do that.  So it
would seem fair to offer a helper function for this operation.

* Include <linux/ata.h> directly instead of through <linux/hdreg.h>.

ab943a2e12 USB: gadget: gadget zero uses new suspend/resume hooks
Use the new device-level suspend/resume hooks for Gadget Zero;
always enable them with the OTG test mode; and support remote
wakeup on both configurations even in non-OTG mode.

This ensures that both configurations can pass the USBCV remote
wakeup tests when the OTG test mode is enabled.  This changes
behavior by adding autoresume support to the loopback config
even in non-OTG mode; the test failure was that it didn't work
in OTG mode.

Yes, we should have device-level suspend/resume callbacks

scenario (with gadget zero in OTG test mode) that's awkward
to handle without it.

71d2718f25 USB: more u32 conversion after transfer_buffer_length and actual_length
transfer_buffer_length and actual_length have become unsigned, therefore some
additional conversion of local variables, function arguments and print
specifications is desired.

A test for a negative urb->transfer_buffer_length became obsolete; instead
we ensure that it does not exceed INT_MAX. Also, urb->actual_length is always
less than urb->transfer_buffer_length.

rh_string() does no longer return -EPIPE in the case of an unsupported ID.
Instead its only caller, rh_call_control() does the check.

This is really a follow up to the modifications Alan Cox made for commit
95da310e66 to pass a tty_struct to various
interface functions, which broke the serial configuration (termios) functions
when the device is being used as a console. These changes restore the
configuration to proper functioning both as a tty and as a console.  As Alan
notes in that commit, these changes will need to be tweaked when we have
a proper console abstraction.

1b8fb4141e USB: ipaq: handle 4 endpoint devices
The ipaq driver currently enforces one port on all devices. This
is correct for 2 and 3 endpoint devices, but with 4 endpoint devices
meaningful communication occurs on the second pair.

This patch allows 2 ports for 4 endpoint devices.

Lots of users are getting confused about the cp2101 driver.  It really
does support more than just the cp2101 device, so rename it to cp210x to
try to prevent confusion.

ef8b6bcb39 USB: CP2101 Support AN205 baud rates
This patch adds support for the extended range of baud rates supported
by CP2102 and CP2103 devices described in SiLabs AN205.  An additional
function cp2101_quantise_baudrate rounds the baud rate as per AN205
Table 1.  A modification to the baud rate calculation removes a rounding
error, allowing the full range of baud rates to be used.

4fe0387afa USB: don't send Set-Interface after reset
This patch (as1221) changes the way usbcore reinitializes a device
following a reset or a reset-resume.  Currently we call
usb_set_interface() for every interface in the active configuration;
this is to put the interface into the same altsetting as before the
reset and to make sure that the host's endpoint state matches the
device's endpoint state.

However, sending a Set-Interface request is a waste of time if an
interface was already in altsetting 0 before the reset, since it is
certainly in altsetting 0 afterward.  In addition, many devices can't
handle Set-Interface requests -- they crash when they receive them.

So instead, the patch adds code to check each interface.  If the
interface wasn't in altsetting 0 before the reset, we go head with the
Set-Interface request as before.  But if it was then we skip sending
the Set-Interface request, and we clear out the host-side endpoint
state by calling usb_disable_interface() followed by
usb_enable_interface().

The patch also adds a couple of new comments to explain what's going
on.
