Current calculation does not take into account any changes to M2 divisor, and

tty_port: If we are opened non blocking we still need to raise the carrier

Original discussion:
http://thread.gmane.org/gmane.linux.usb.general/23217/focus=23248
or
http://marc.info/?l=linux-usb&m=125553790714133&w=2

The tty_port code inherited a bug common to various drivers it was based
upon. If the tty is opened O_NONBLOCK we do not wait for the carrier to be
raised but we must still raise our modem lines if appropriate.

(There is a second question here about whether we should do so if CLOCAL is
 set but that can wait)

tty: cp210x: Fix carrier handling

9a68e39d4a701fb3be03cae9b462408664ebd205 broke carrier handling so that a
cp210x setup which needed the carrier lines set up (non CLOCAL) which did
not make a call which set the termios bits left the lines down even if
CLOCAL was not asserted.

Fix this not by reverting but by adding the proper dtr_rts and
carrier_raised methods. This both sets the modem lines properly and also
implements the correct blocking semantics for the port as required by
POSIX.

I have the same problem with cdc-acm (I'm using a Samsung SGH-U900): when I
unplug it from the USB port during a PPP connection, the ppp daemon gets the
hangup correctly (and closes the device), but the struct acm corresponding to
the device disconnected is not freed. Hence reconnecting the device results in
creation of /dev/ttyACM(x+1). The same happens when the system is hibernated
during a PPP connection.

This memory leak is due to the fact that when the tty is hung up,
tty_port_close_start() returns always zero, and acm_tty_close() never reaches
the point where acm_tty_unregister() is called.

Here is a fix for this.

USB: xhci: Fix bug memory free after failed initialization.

USB: xhci: Fix TRB physical to virtual address translation.

The trb_in_td() function in the xHCI driver is supposed to translate a
physical transfer buffer request (TRB) into a virtual pointer to the ring
segment that TRB is in.

Unfortunately, a mistake in this function may cause endless loops as the
driver searches through the linked list of ring segments over and over
again.  Fix a couple bugs that may lead to loops or bad output:

1. Bail out if we get a NULL pointer when translating the segment's
private structure and the starting DMA address of the segment chunk.  If
this happens, we've been handed a starting TRB pointer from a different
ring.

2. Make sure the function works when there's multiple segments in the
ring.  In the while loop to search through the ring segments, use the
current segment variable (cur_seg), rather than the starting segment
variable (start_seg) that is passed in.

3. Stop searching the ring if we've run through all the segments in the
ring.

USB: usbmon: fix bug in mon_buff_area_shrink

This patch (as1299b) fixes a bug in an error-handling path of usbmon's
binary interface.  The storage area for URB data is divided into
fixed-size blocks.  If an URB's data can't be copied, the area
reserved for it should be decreased to the size of the truncated
information (rounded up to a block boundary).  Rounding up the amount
to be removed and subtracting it from the reserved size is definitely
the wrong thing to do.

Also, when the data for an isochronous URB can't be copied, we can
still copy the isoc packet descriptors.  In fact the current code does
copy the descriptors, but then sets the capture length to 0 so they
remain inaccessible.  The capture length should be reduced to the
length of the descriptors, not set to 0.
