This reverts commit 806e8f8fcc.
To quote Alan Stern:
The necessity for this patch has been under discussion.
It turns out the UDC that Mian has been working on and Felipe's
UDC have contradictory requirements. Mian's UDC driver wants a
bulk-OUT transfer length to be shorter than the maxpacket size
if a short packet is expected, whereas Felipe's UDC hardware
always needs bulk-OUT transfer lengths to be evenly divisible by
the maxpacket size.
Mian has agreed to go back over the driver to resolve this
conflict. This means we probably will not want this patch after
all. (In fact, we may ultimately decide to change the gadget
framework to require that bulk-OUT transfer lengths _always_ be
divisible by the maxpacket size -- only the g_file_storage and
g_mass_storage gadgets would need to be changed.)

This patch (as1455) removes the extra padding sent by g_file_storage
and g_mass_storage when the gadget wants to send less data than
requested by the host and isn't allowed to halt the bulk-IN endpoint.
Although the Bulk-Only Transport specification requires the padding to
be present, it isn't truly needed since the transfer will be terminated
by a short packet anyway. Furthermore, many existing devices don't
bother to send any padding.

Mass-storage and file-storage gadgets align the length to maximum-packet-size
when preparing the request to receive CBW. This is unnecessary and prevents the
controller driver from knowing that a short-packet is expected.
It is incorrect to set short_not_ok when preparing the request to receive CBW.
CBW will be a short-packet so short_not_ok must not be set.
This makes bh->bulk_out_intended_length unnecessary so it is also removed.

The driver did not take the zero flag in the USB request. If the
request length is the same as the endpoint's maxpacket, an additional
ZLP with no data has to be transmitted.
The method used here is inspired to what is done in fsl_udc_core.c
(and pxa27x_udc.c and at91_udc.c) where this is supported.

Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size. Change the USB core's hub descriptor to have a
union for the last fields that differ. Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.
Translate the new version of the hub port status field into the old
version that khubd understands. (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)
Add new code to handle link state change status. Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.
This patch is a modified version of the original patch submitted by John

Using a #define to redefine a common variable name is a bad thing,
especially when the #define is in a header. include/linux/usb/hcd.h
redefined bitmap to DeviceRemovable to avoid typing a long field in the
hub descriptor. This has unintended side effects for files like
drivers/usb/core/devio.c that include that file, since another header
included after hcd.h has different variables named bitmap.
Remove the bitmap #define and replace instances of it in the host
controller code. Cleanup the spaces around function calls and square
brackets while we're at it.

This is a patch that seems to make the USB hangs on the S3C244X go away.
At least a good amount of ping torture didn't make them come back so far.
The issue is that, if there are several back-to-back packets, sometimes no
interrupt is generated for one of them. This seems to be caused by the
mysterious dual packet mode, which the USB hardware enters automatically
if the endpoint size is half that of the FIFO. (On the 244X, this is the
normal situation for bulk data endpoints.)
There is also a timing factor in this. It seems that what happens is that
the USB hardware automatically sends an acknowledgement if there is only one
packet in the FIFO (the FIFO has space for two). If another packet arrives
before the host has retrieved and acknowledged the previous one, no interrupt
is generated for that second one.
However, there may be an indication. There is one undocumented bit (none
of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set
suspiciously often when this condition occurs. There is also
CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to
this. (The Samsung manual is rather terse on that, as usual.)
This needs to be examined further. For now, the patch seems to do the
trick.
