When a non-PCI device is passed to that function it might
pass group == NULL to iommu_group_add_device() which then
dereferences it and cause a crash this way. Fix it by
just returning an error for non-PCI devices.

Commit 6cfec04bcc05 ("regmap: Separate regmap dev initialization") moved the
regmap debugfs initialization after regcache initialization. This means
that the regmap debugfs directory is not created yet when the cache
initialization runs and so any debugfs files registered by the regcache are
created in the debugfs root directory rather than the debugfs directory of
the regmap instance. Fix this by adding a separate callback for the
regcache debugfs initialization which will be called after the parent
debugfs entry has been created.

Interrupt is enabled when bind_interdomain_evtchn_to_irqhandler returns.
If there's interrupt pending interrupt handler is invoked.
NAPI needs to be initialised before binding interrupt otherwise the
interrupt handler will try to scheduling a NAPI instance that is not
initialised yet, resulting in kernel OOPS.
This fixes a regression introduced in ea2c5e13 ("xen-netback: move NAPI
add/remove calls").
Ideally function calls to create kthreads should also be moved before
binding but I intent to fix this regression with minimal changes and
refactor the code with another patch.

This device claims TSO support for vlans. It also allows a user to
control vlan acceleration offloading. As such, it is possible to turn
off vlan acceleration and configure a vlan which will continue to send
TSO traffic.
In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO information.
This results in corrupted frames sent on the wire.
This patch extracts the protocol value correctly by using a
vlan_get_protocol() helper and corrects corrupt TSO frames.

This driver doesn't appear to support vlan acceleration at
all. However, it does claim to support TSO and IP checksums
for vlan devices. Thus any configured vlan device would
end up passing down partial checksums or TSO frames.
The driver also uses the value from skb->protocol to
determine TSO and checksum offload information, but assumes
that skb->protocol holds the l3 protocol information.
As a result, vlan traffic with partial checksums or TSO
will fail those checks and TSO will not happen.
Fix this by using vlan_get_protocol() helper.

The driver claims that it can do TSO and IP checksums on vlan
devices and also allows user to control vlan acceleration offloading.
This makes it possible to push traffic to this driver that has TSO or
partial checksums set, but also have a non-accelearted vlan
header. In this case, the driver will fail to correctly
identify such traffic and will not correctly perform
segmentation and checksum calculation.
Fix this by using vlan_get_protocol() helper instead of
assuming skb->protocol always has this information.

previous QR_EC
There is platform refusing to respond QR_EC when SCI_EVT isn't set
which is Acer Aspire V5-573G.
By disallowing QR_EC to be issued before the previous one has been
completed we are able to reduce the possibilities to trigger issues on
such platforms.
Note that this fix can only reduce the occurrence rate of this issue, but
this issue may still occur when such a platform doesn't clear SCI_EVT
before or immediately after completing the previous QR_EC transaction.
This patch cannot fix the CLEAR_ON_RESUME quirk which also relies on
the assumption that the platforms are able to respond even when SCI_EVT
isn't set.
But this patch is still useful as it can help to reduce the number of
scheduled QR_EC work items.

There is a platform refusing to respond QR_EC when SCI_EVT isn't set
(Acer Aspire V5-573G).
Currently, we rely on the behaviour that the EC firmware can respond
something (for example, 0x00 to indicate "no outstanding events") to
QR_EC even when SCI_EVT is not set, but the reporter has complained
about AC/battery pluging/unpluging and video brightness change delay
on that platform.
This is because the work item that has issued QR_EC has to wait until
timeout in this case, and the _Qxx method evaluation work item queued
after QR_EC one is delayed.
It sounds reasonable to fix this issue by:
1. Implementing SCI_EVT sanity check before issuing QR_EC in the EC
driver's main state machine.
2. Moving QR_EC issuing out of the work queue used by _Qxx evaluation
to a seperate IRQ handling thread.
This patch fixes this issue using solution 1.
By disallowing QR_EC to be issued when SCI_EVT isn't set, we are able to
handle such platform in the EC driver's main state machine. This patch
enhances the state machine in this way to survive with such malfunctioning
EC firmware.
Note that this patch can also fix CLEAR_ON_RESUME quirk which also relies
on the assumption that the platforms are able to respond even when SCI_EVT
isn't set.

Currently, notify callbacks for fixed button events are run from
interrupt context. That is not necessary and after commit 0bf6368ee8f2
(ACPI / button: Add ACPI Button event via netlink routine) it causes
netlink routines to be called from interrupt context which is not
correct.
Also, that is different from non-fixed device events (including
non-fixed button events) whose notify callbacks are all executed from
process context.
For the above reasons, make fixed button device notify callbacks run
in process context which will avoid the deadlock when using netlink
to report button events to user space.

We generally don't allow ACPI drivers to bind to ACPI device objects
that companion "physical" device objects are created for to avoid
situations in which two different drivers may attempt to handle one
device at the same time. Recent ACPI device enumeration rework
extended that approach to ACPI PNP devices by starting to use a scan
handler for enumerating them. However, we previously allowed ACPI
drivers to bind to ACPI device objects with existing PNP device
companions and changing that led to functional regressions on some
systems.
For this reason, add a special check for PNP devices in
acpi_device_probe() so that ACPI drivers can bind to ACPI device
objects having existing PNP device companions as before.

commit 65b97cf6b8de introduced in v3.7 caused a regression
by using a reversed CS_MASK thus causing omap_calculate_ecc to
always fail. As the NAND base driver never checks for .calculate()'s
return value, the zeroed ECC values are used as is without showing
any error to the user. However, this won't work and the NAND device
won't be guarded by any error code.
Fix the issue by using the correct mask.
Code was tested on omap3beagle using the following procedure
- flash the primary bootloader (MLO) from the kernel to the first
NAND partition using nandwrite.
- boot the board from NAND. This utilizes OMAP ROM loader that
relies on 1-bit Hamming code ECC.

For v3.12 and prior, 1-bit Hamming code ECC via software was the
default choice. Commit c66d039197e4 in v3.13 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.12
and prior to be unusable in v3.13 and later. So revert back to
using software ECC by default if an ECC scheme is not explicitely
specified.
This defect can be observed on the following boards during legacy boot

-omap3touchbook

After commit 174beab7d445 ("at76c50x-usb: Don't perform DMA from stack memory")
at76_delete_device() and usb_put_dev() are called both
if at76_init_new_device() fails in at76_probe().
But at76_delete_device() does usb_put_dev(priv->dev) itself
that means double usb_put_dev().
The patch avoids the problem by moving usb_put_dev() from
at76_delete_device() to at76_disconnect().
Found by Linux Driver Verification project (linuxtesting.org).

The uSCSI from Newer Technology is a SCSI-USB converter with USB ID 06ca:2003.
Like several other SCSI-USB products, it's a Shuttle Technology OEM device.
Without a suitable entry in unusual-devs.h, the converter can only access the
(single) device with SCSI ID 0. Copying the entry for device 04e6:0002 allows
it to work with devices with other SCSI IDs too.
There are currently six entries for Shuttle-developed SCSI-USB devices in
unusual-devs.h (grep for euscsi):
04e6:0002 Shuttle eUSCSI Bridge USB_SC_DEVICE, USB_PR_DEVICE
04e6:000b Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK
04e6:000c Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK
050d:0115 Belkin USB SCSI Adaptor USB_SC_SCSI, USB_PR_BULK
07af:0004 Microtech USB-SCSI-DB25 USB_SC_DEVICE, USB_PR_DEVICE
07af:0005 Microtech USB-SCSI-HD50 USB_SC_DEVICE, USB_PR_DEVICE
lsusb -v output for the uSCSI lists
bInterfaceSubClass 6 SCSI
bInterfaceProtocol 80 Bulk (Zip)
This patch adds an entry for the uSCSI to unusual_devs.h.

This was used back when usbip-host was an interface device driver;
after the conversion to device driver, the table remained unused.
Remove it in order to stop receiving a warning about it.
