Bjørn Mork 15699e6faf USB: cdc-wdm: Avoid hanging on interface with no USB_CDC_DMM_TYPE
The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces.  A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files.  But this would fail with a 0 buffer length
due to the missing descriptor.

Fix by defining a reasonable fallback size: The minimum
device receive buffer size required by the CDC WMC standard,
revision 1.1

Alan Stern 194b3af4eb USB: OHCI: fix new compiler warnings
This patch (as1515) fixes some unavoidably dumb compiler warnings:

  CC [M]  drivers/usb/renesas_usbhs/mod.o
In file included from drivers/usb/host/ohci-hcd.c:101:0:
drivers/usb/host/ohci-dbg.c: In function ‘fill_registers_buffer’:
drivers/usb/host/ohci-dbg.c:656:2: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]
drivers/usb/host/ohci-dbg.c:675:3: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]

Instead of trying to fix the macro to work under all cirumstances,
just add a second macro for use in cases where the "next" argument is
the address of a local variable.

Unfortunately the macro cannot be replaced by a real subroutine,
because there's no va_list version of ohci_dbg() or dev_dbg().

	Looks you have queued the patch into your tree, but just now I
	find the patch is not needed at all, since we have had
	minor_rwsem(drivers/usb/core/file.c) for this purpose, please
	drop the patch, sorry for it.

The newer cp2104 devices require the baud rate to be initialised after
power on. Make sure it is set when port is opened.

Preston Fick 7f482fc88a USB: cp210x: fix CP2104 baudrate usage
This fix changes the way baudrates are set on the CP210x devices from
Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV
command, and GET/SET_BAUDRATE command, while CP2104 and higher devices
only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in
kernel version 3.2.0 only implements the GET/SET_BAUDDIV command.

This patch implements the two new codes for the GET/SET_BAUDRATE
commands. Then there is a change in the way that the baudrate is
assigned or retrieved. This is done according to the CP210x USB
specification in AN571. This document can be found here:
http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart

Sections 5.3/5.4 describe the USB packets for the old baudrate method.
Sections 5.5/5.6 describe the USB packets for the new method. This
patch also implements the new request scheme, and eliminates the
unnecessary baudrate calculations since it uses the "actual baudrate"
method.

This patch solves the problem reported for the CP2104 in bug 42586,
and also keeps support for all other devices (CP2101/2/3).

This patchfile is also attached to the bug report on
bugzilla.kernel.org. This patch has been developed and test on the
3.2.0 mainline kernel version under Ubuntu 10.11.

Fix regression introduced by commit b1ffb4c851 ("USB: Fix Corruption
issue in USB ftdi driver ftdi_sio.c") which caused the termios settings
to no longer be initialised at open. Consequently it was no longer
possible to set the port to the default speed of 9600 baud without first
changing to another baud rate and back again.
