libata passes the returned value of dma_map_sg() to

To unmap a scatterlist, just call:
pci_unmap_sg(pdev, sglist, nents, direction);
Again, make sure DMA activity has already finished.
PLEASE NOTE: The 'nents' argument to the pci_unmap_sg call must be
the _same_ one you passed into the pci_map_sg call,
it should _NOT_ be the 'count' value _returned_ from the
pci_map_sg call.

When booting Xen Dom0 on a pre-release 3.2.1 hypervisor the system Oopses on a
"Unable to handle kernel NULL pointer dereference" in xenwatch.
From the backtrace it looks like backend_changed is calling bdget_disk
with a NULL pointer. Checking for NULL and returning ENODEV instead
allows the kernel to boot.

The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up. This patch adds the device id to cdc_ether.c as a workaround.
Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c. See also

This is 2nd attempt to implement the initialization/reading of MAC address
from EEPROM. The first used PCI's VPD and there were some problems, some
devices are not able to read EEPROM content by VPD. The 2nd one uses direct
access to EEPROM through bit-banging interface and my testing results seem
to be much better.
I tested 5 systems each with different Realtek NICs and I didn't find any
problem. AFAIK Francois's NICs also works fine.
Original description:
This fixes the problem when MAC address is set by ifconfig or by
ip link commands and this address is stored in the device after
reboot. The power-off is needed to get right MAC address.
This is problem when Xen daemon is running because it renames the device
name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF.
After reboot the device is still using FE:FF:FF:FF:FF:FF.

The musb_h_disable() routine can oops in some cases:
- It's not safe to read hep->hcpriv outside musb->lock,
since it gets changed on completion IRQ paths.
- The list iterators aren't safe to use in that way;
just remove the first element while !list_empty(),
so deletions on other code paths can't make trouble.
We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint. That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.
Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback). Since a QH with an empty URB
list is now supposed to be freed, do that. And remove a now-useless
check from musb_advance_schedule().

The input queue should be used for TX on endpoints which
share FIFO hardware. The host TX path wasn't doing that.
Shared FIFOs are most often configured for periodic endpoints,
which are mostly used for RX/IN transfers ... that's probably
how this bug managed to linger for a long time.

Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:
- Use clk_enable()/clk_disable() ... the "always enable USB clocks"
code this originally relied on has since been removed.
- Initialize the USB device only after the relevant I2C GPIOs are
available, so the host side can properly enable VBUS.
- Tweak init sequencing to cope with mainline's relatively late init
of the I2C system bus for power switches, transceivers, and so on.
Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also
verified on OMAP3.
(Unrelated: correct the MODULE_PARM_DESC spelling of musb_debug.)

This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter. This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor! The
usb_get_string() routine needs to check whether it got the right
type of descriptor.
Oddly enough, this sort of check is already present in
usb_get_descriptor(). The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state. This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.
This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.
This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

Disable the SSB core on device shutdown.
This has two advantages:
1) A clean device shutdown is always desired here, because we disable
the device's global crystal in the next statement.
2) This fixes a bug where the device will come up with the enable-bit
set on the next initialization (without a reboot inbetween).
This causes breakage on the second initialization due to code that
checks this bit (ssb_device_is_enabled() checks).

With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.
There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.
This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.
This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.
For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),
this patch fixes errors like:
