DCP data/status stage needs ureq to usbhs_pkt_push(),
but sometimes, there is no data stage.
In that case, allocated ureq was not freed,
Current ureq alloc/free pair were difficult to understand.
This patch removed unnecessary/un-understandable ureq alloc
from usbhsh_urb_enqueue(), and create simpler alloc/free pair.

With Peiyu's patch "gadget: mass_storage: adapt logic block size to bound block
devices" (http://www.spinics.net/lists/linux-usb/msg50791.html), now mass storage
can adjust logic block size dynamically based on real devices.
Then there is one issue caused by it, if two luns have different logic block size,
mass storage can't work.
Let's check the current software flow:
1. get_next_command(): call received_cbw();
2. received_cbw(): update common->lun = cbw->Lun, but common->curlen is not updated;
3. do_scsi_command(): in READ_X and WRITE_X commands, common->data_size_from_cmnd is
updated by common->curlun->blkbits;
4. check_command(): update common->curlun according to common->lun
As you can see, the step 3 uses wrong common->curlun, then wrong common->curlun->blkbits.
If the two luns have same blkbits, there isn't issue. Otherwise, both will fail.
This patch moves the common->curlun update to step 1, then make sure step 3 gets right
blkbits and data_size_from_cmnd.

The ci13xxx_udc driver checks the number of endpoints in the udc
controller, however some routines expect that the hardware has 16
bidirectional endpoints.
This patch improves the driver to work on controllers with less than
16 endpoints like the udc controller found on freescale's
mx23 and mx28.

For the Asus 1101HA, reporting position by reading the DMA position
buffer map seems unstable and often wrong. The reporter says that
position_fix=LPIB works much better (although not 100%, but this is
probably due to other issues).
The controller chip is an Intel Poulsbo 8086:811b (rev 07) controller,

This function can wait for 5min under certain scenarios. One of them is when
the port is down from switch and bus reset is issued. The bus reset used to
wait for 5 minutes for the loop and upper layer callers used to hang and give
stack trace because of getting stuck for 120 sec. It is legacy code that was
used when the driver used to do queuing of the commands.

Adds support for the Cintiq 24HD. There are two quirks about this
model that haven't been seen in prior tablets. First, a second
touch ring is present on this display; it is being exposed via the
ABS_THROTTLE axis. Second, three capacitive buttons at the top of
the unit are available; though physically a touch strip, we report
the use of these buttons with generic KEY_ events.

Synaptics touchpads on several Dell laptops, particularly Vostro V13
systems, may not respond properly to PS/2 commands and queries immediately
after resuming from suspend to RAM. This leads to unresponsive touchpad
after suspend/resume cycle.
Adding a 1-second delay after resetting the device allows touchpad to
finish initializing (calibrating?) and start reacting properly.

This driver adds support for Sharp's GP2AP002A00F proximity sensor. The
proximity is measured as a binary switch, i.e. an object is either
detected or not detected. Hence, this driver is implemented as a switch
that reports SW_FRONT_PROXIMITY.
