Make the driver aware of the initial status of the regulator.
The leds-regulator driver was ignoring the initial status of the
regulator; this resulted in rdev->use_count being incremented to 2 after
calling regulator_led_set_value() in the .probe method when a regulator
was already enabled at insmod time, which made it impossible to ever
disable the regulator.

This reverts commit 5808544690.
To quote Richard:
I don't think this should be mainlined. It was a
misunderstanding on my part. If you see all the other hdc
drivers in the same location, they all do the same thing (i.e.
clear the interrupt status first, then do the work) that
"glitch" I think I saw was actually two back-to-back
interrupts.
Sebastian (the original author of isp1760) explained it to me a
few days after my submission.

This patch disable the optional PM feature inside the Hudson3 platform under
the following conditions:
1. If an isochronous device is connected to xHCI port and is active;
2. Optional PM feature that powers down the internal Bus PLL when the link is
in low power state is enabled.
The PM feature needs to be disabled to eliminate PLL startup delays when the
link comes out of low power state. The performance of DMA data transfer could
be impacted if system delay were encountered and in addition to the PLL start
up delays. Disabling the PM would leave room for unpredictable system delays
in order to guarantee uninterrupted data transfer to isochronous audio or
video stream devices that require time sensitive information. If data in an
audio/video stream was interrupted then erratic audio or video performance
may be encountered.
AMD PLL quirk is already implemented in OHCI/EHCI driver. After moving the
quirk code to pci-quirks.c and export them, xHCI driver can call it directly
without having the quirk implementation in itself.

On a resume, when the power is lost during hibernate, the USB core will

If I unplug a device while the UAS driver is loaded, I get an oops
in usb_free_streams(). This is because usb_unbind_interface() calls
usb_disable_interface() which calls usb_disable_endpoint() which sets
ep_out and ep_in to NULL. Then the UAS driver calls usb_pipe_endpoint()
which returns a NULL pointer and passes an array of NULL pointers to
usb_free_streams().
I think the correct fix for this is to check for the NULL pointer
in usb_free_streams() rather than making the driver check for this
situation. My original patch for this checked for dev->state ==
USB_STATE_NOTATTACHED, but the call to usb_disable_interface() is
conditional, so not all drivers would want this check.
Note from Sarah Sharp: This patch does avoid a potential dereference,
but the real fix (which will be implemented later) is to set the
.soft_unbind flag in the usb_driver structure for the UAS driver, and
all drivers that allocate streams. The driver should free any streams
when it is unbound from the interface. This avoids leaking stream rings
in the xHCI driver when usb_disable_interface() is called.
This should be queued for stable trees back to 2.6.35.

Currently, when resetting a device, xHCI driver disables all but one
endpoints and frees their rings, but leaves alone any streams that
might have been allocated. Later, when users try to free allocated
streams, we oops in xhci_setup_no_streams_ep_input_ctx() because
ep->ring is NULL.
Let's free not only rings but also stream data as well, so that
calling free_streams() on a device that was reset will be safe.
This should be queued for stable trees back to 2.6.35.

When we get a port status change event, we need to figure out what type of
port it came from: a USB 3.0 port, or a USB 2.0/1.1 port. We can't know
which usb_hcd to use until that point, so hcd will be NULL for part of the
function. Unfortunately, if any of the sanity checks fail, we'll jump to
the cleanup label before hcd is set to a valid pointer, and then we'll
attempt to tell the USB core to kick the hcd, which is NULL.
Skip kicking the roothub if the sanity checks fail.

When parsing exponent-expressed intervals we subtract 1 from the
value and then expect it to match with original + 1, which is
highly unlikely, and we end with frequent spew:
usb 3-4: ep 0x83 - rounding interval to 512 microframes
Also, parsing interval for fullspeed isochronous endpoints was
incorrect - according to USB spec they use exponent-based
intervals (but xHCI spec claims frame-based intervals). I trust
USB spec more, especially since USB core agrees with it.
This should be queued for stable kernels back to 2.6.31.

In addition, it caused compiler warning since the compiler could

This patch (as1458) fixes a problem affecting ultra-reliable systems:
When hardware failover of an EHCI controller occurs, the data
structures do not get released correctly. This is because the routine
responsible for removing unused QHs from the async schedule assumes
the controller is running properly (the frame counter is used in
determining how long the QH has been idle) -- but when a failover
causes the controller to be electronically disconnected from the PCI
bus, obviously it stops running.
The solution is simple: Allow scan_async() to remove a QH from the
async schedule if it has been idle for long enough _or_ if the
controller is stopped.

DMA mode 1 data corruption anomaly on Blackfin systems. This issue is
specific to the Blackfin silicon as the bug appears to be related to the
connection of the musb ip to the bus/dma fabric.
Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
DMA mode 1 allows large size transfers to generate a single interrupt
at the end of the entire transfer. The transfer is split up in packets
of length specified in the Maximum Packet Size field for that endpoint.
If the transfer size is not an integer multiple of the Maximum Packet
Size, a short packet will be present at the end of the transfer.
Under certain conditions this packet may be corrupted in the USB FIFO.
Workaround:
Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
mode 0 to transfer the short packet.
As an example if your transfer size is 33168 bytes and Maximum Packet
Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
the remainder (33168 mod 512) in DMA mode 0.

Due to the recent changes to musb's glue layers,
we can't compile musb-hdrc as a module - compilation
will break due to undefined symbol musb_debug. In
order to fix that, we need a big re-work of the
debug support on the MUSB driver.
Because that would mean a lot of new code coming
into the -rc series, it's best to defer that to
next merge window and for now just disable module
support for MUSB.
Once we get the refactor of the debugging support
done, we can simply revert this patch and things
will go back to normal again.

As per Konrad's original patch, the dummy page used
by the gart code and allocated in radeon_gart_init()
was not freed properly in radeon_gart_fini().
At the same time r6xx and newer allocated and freed the
dummy page on their own. So to do Konrad's patch one
better, just remove the allocation and freeing of the
dummy page in the r6xx, 7xx, evergreen, and ni code and
allocate and free in the gart_init/fini() functions for
all asics.

Subject: [PATCH] thinkpad-acpi: Some BIOS versions don't end in WW, remove check
My X201s BIOS version string is 6QET46V1 (1.16 ). The
EC version string is 6QHT28WW-1.09. The driver was requiring that both
of these have 'WW' in positions 6 and 7. I don't know what the
significance of having 'V1' there instead is, but removing the test
makes the driver load on my machine.

function tests nonexistent member of pxafb_info (since the member is not

In order for MFD drivers to fetch their cell pointer but also their
platform data one, an mfd cell pointer is added to the platform_device
structure.
That allows all MFD sub devices drivers to be MFD agnostic, unless
they really need to access their MFD cell data. Most of them don't,
especially the ones for IPs used by both MFD and non MFD SoCs.

Xen save/restore is going to use hibernate device callbacks for
quiescing devices and putting them back to normal operations and it
would need to select CONFIG_HIBERNATION for this purpose. However,
that also would cause the hibernate interfaces for user space to be
enabled, which might confuse user space, because the Xen kernels
don't support hibernation. Moreover, it would be wasteful, as it
would make the Xen kernels include a substantial amount of code that
they would never use.
To address this issue introduce new power management Kconfig option
CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code
that is necessary for the hibernate device callbacks to work and make
CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to
select CONFIG_HIBERNATE_CALLBACKS without dragging the entire
hibernate code along with it.

In commit 13583b1659 ("PCI: refactor io size calculation code") Ram
had a thinko in the refactorization of the code: the end result used the
variable 'align' for the bus alignment, but the original code used
'min_align'.
Since then, another use of that 'align' variable got introduced by
commit c8adf9a3e8 ("PCI: pre-allocate additional resources to devices
only after successful allocation of essential resources.")
Fix both of those uses to use 'min_align' as they should.
