The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write.  On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.

If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.

The driver incorrectly cancels the mass-storage device CSW request
(which leads to device reset) due to giving back URB at the head of
endpoint's queue after sending each STALL handshake; stop doing that
and start checking for the queue being non-empty before stalling an
endpoint and disallowing stall in such case in musb_gadget_set_halt()
like the other gadget drivers do.

Moreover, the driver starts Rx request despite of the endpoint being
halted -- fix this by moving the SendStall bit check from musb_g_rx()
to rxstate().  And we also sometimes get into rxstate() with DMA still
active after clearing an endpoint's halt (not clear why), so bail out
in this case, similarly to what txstate() does...

While at it, also do the following changes :

- in musb_gadget_set_halt(), remove pointless Tx FIFO flushing (the
  driver does not allow stalling with non-empty Tx FIFO anyway);

- in rxstate(), stop pointlessly zeroing the 'csr' variable;

- in musb_gadget_set_halt(), move the 'done' label to a more proper
  place;

- in musb_g_rx(), eliminate the 'done' label completely...

This patch (as1304) fixes a regression in ehci-hcd.  Evidently some
hubs don't handle Clear-TT-Buffer requests correctly, so we should
avoid sending them when they don't appear to be absolutely necessary.
The reported symptom is that output on a downstream audio device cuts
out because the hub stops relaying isochronous packets.

The patch prevents Clear-TT-Buffer requests from being sent following
a STALL handshake.  In theory a STALL indicates either that the
downstream device sent a STALL or that no matching TT buffer could be
found.  In either case, the transfer is completed and the TT buffer
does not remain busy, so it doesn't need to be cleared.

Also, the patch fixes a minor flaw in the code that actually sends the
Clear-TT-Buffer requests.  Although the pipe direction isn't really
used for control transfers, it should be a Send rather than a Receive.

In 2.6.23 kernel, commit a32ea1e1
("Fix read/truncate race") fixed a race in the generic code, and as a
side effect, now do_generic_file_read() can ask us to readpage() past
the i_size. This seems to be correctly handled by the block routines
(e.g. block_read_full_page() fills the page with zeroes in case if
somebody is trying to read past the last inode's block).

JFFS2 doesn't handle this; it assumes that it won't be asked to read
pages which don't exist -- and thus that there will be at least _one_
valid 'frag' on the page it's being asked to read. It will fill any
holes with the following memset:

  memset(buf, 0, min(end, frag->ofs + frag->size) - offset);

When the 'closest smaller match' returned by jffs2_lookup_node_frag() is
actually on a previous page and ends before 'offset', that results in:

  memset(buf, 0, <huge unsigned negative>);

Hopefully, in most cases the corruption is fatal, and quickly causing
random oopses, like this:

This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with
JFFS2 filesystem that were failing since 2.6.23 (seems like the bug
above also broke the truncation).

smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt
flags to be taken from the resource structure.  However, d280eadc
changed this to checking for non-zero resource flags.

Unfortunately, this means that on some platforms, we end up passing
'-1' to request_irq rather than the desired result.  Combine the two
conditions into one so that the IRQ flags are taken from the resource
if either SMC_IRQ_FLAGS is -1 or the resource flags specify an
interrupt trigger.

This restores network on at least the Versatile platform.

But it brought other problem for which it is necessary to introduce a new
