The vmw_pvscsi driver reports most successful aborts as FAILED to the
scsi error handler. This is do to a misunderstanding of how
completion_done() works and its interaction with a successful wait using
wait_for_completion_timeout(). The vmw_pvscsi driver is expecting
completion_done() to always return true if complete() has been called on
the completion structure. But completion_done() returns true after
complete() has been called only if no function like
wait_for_completion_timeout() has seen the completion and cleared it as
part of successfully waiting for the completion.
Instead of using completion_done(), vmw_pvscsi should just use the
return value from wait_for_completion_timeout() to know if the wait
timed out or not.

While merging mpt3sas & mpt2sas code, we added the is_warpdrive check
condition on the wrong line
---------------------------------------------------------------------------
scsih_target_alloc(struct scsi_target *starget)
sas_target_priv_data->handle = raid_device->handle;
sas_target_priv_data->sas_address = raid_device->wwid;
sas_target_priv_data->flags |= MPT_TARGET_FLAGS_VOLUME;
- raid_device->starget = starget;
+ sas_target_priv_data->raid_device = raid_device;
+ if (ioc->is_warpdrive)
+ raid_device->starget = starget;
}
spin_unlock_irqrestore(&ioc->raid_device_lock, flags);
return 0;
------------------------------------------------------------------------------
That check should be for the line sas_target_priv_data->raid_device =
raid_device;
Due to above hunk, we are not initializing raid_device's starget for
raid volumes, and so during raid disk deletion driver is not calling
scsi_remove_target() API as driver observes starget field of
raid_device's structure as NULL.

In commit 9a56e5d6a0ba ("Drivers: hv: make VMBus bus ids persistent")
the name of vmbus devices in sysfs changed to be (in 4.9-rc1):
/sys/bus/vmbus/vmbus-6aebe374-9ba0-11e6-933c-00259086b36b
The prefix ("vmbus-") is redundant and differs from how PCI is
represented in sysfs. Therefore simplify to:
/sys/bus/vmbus/6aebe374-9ba0-11e6-933c-00259086b36b
Please merge this before 4.9 is released and the old format
has to live forever.

usb: fixes for v4.9-rc4
Three more fixes for current -rc cycle. One
randbuild fix on dwc3-st which was lacking
<linux/pinctrl/consumer.h>, removal of IRQ
throttling for networking gadgets and a fix for
dwc3's error handling on failed initialization.

According to Dave Miller "the networking stack has a
hard requirement that all SKBs which are transmitted
must have their completion signalled in a fininte
amount of time. This is because, until the SKB is
freed by the driver, it holds onto socket,
netfilter, and other subsystem resources."
In summary, this means that using TX IRQ throttling
for the networking gadgets is, at least, complex and
we should avoid it for the time being.

Check whether the kernel really supports power resources for a device,
otherwise the power might not be removed when the device is runtime
suspended (DSM should still work in these cases where PR does not).
This is a workaround for a problem where ACPICA and Windows 10 differ in
behavior. ACPICA does not correctly enumerate power resources within a
conditional block (due to delayed execution of such blocks) and as a
result power_resources is set to false even if _PR3 exists.

At smp_prepare_cpus() we set present cpu mask as part of init
for all CPUs at range [0-max_cpus].
This is done without checking if this mask is already being set.
At platform of eznps this mask is already being initialized at
smp_init_cpus() by using hook plat_smp_ops.init_early_smp().
So to avoid overriding of present cpu mask we check the number of
bits which are set in this mask. At the begin only bit for boot CPU
is set so if number of bits already set is no more than one we can be
assure that there is no overriding of this mask.

while all other nSIM-related .dts files already had
PCT node for quite some time, so adding it now.
Note 2: All defconfigs were regenerated with "make savedefconfig"

Group index is incremented on every new group parsed. Since the
field is part of struct imx_pinctrl_soc_info, which is typically
a global variable passed by the individual pinctrl-imx.c based
driver, it does not get cleared automatically when re-probing the
driver. This lead imx_pinctrl_parse_functions passing a group
pointer which is outside of the allocated group space on second
probe and onwards. Typically this ended up in a NULL pointer
dereference when accessing the name field like this:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
...
PC is at strcmp+0x18/0x44
LR is at imx_dt_node_to_map+0xc4/0x290
Avoid this by setting group_index to 0 on probe.
This has been observed when using DEBUG_TEST_DRIVER_REMOVE.

Sylvain Lemieux reports the LPC32xx GPIO driver is broken since
commit 762c2e46c059 ("gpio: of: remove of_gpiochip_and_xlate() and
struct gg_data"). Probably, gpio-etraxfs.c and gpio-davinci.c are
broken too.
Those drivers register multiple gpio_chip that are associated to a
single OF node, and their own .of_xlate() checks if the passed
gpio_chip is valid.
Now, the problem is of_find_gpiochip_by_node() returns the first
gpio_chip found to match the given node. So, .of_xlate() fails,
except for the first GPIO bank.
Reverting the commit could be a solution, but I do not want to go
back to the mess of struct gg_data. Another solution here is to
take the match by a node pointer and the success of .of_xlate().
It is a bit clumsy to call .of_xlate twice; for gpio_chip matching
and for really getting the gpio_desc index. Perhaps, our long-term
goal might be to convert the drivers to single chip registration,
but this commit will solve the problem until then.

When allocating a new line handle or event a file is allocated that it is
associated to. The file is attached to a file descriptor of the current
process and the file descriptor is returned to userspace using
copy_to_user(). If this copy operation fails the line handle or event
allocation is aborted, all acquired resources are freed and an error is
returned.
But the file struct is not freed and left attached to the userspace
application and even though the file descriptor number was not copied it is
trivial to guess. If a userspace application performs a IOCTL on such a
left over file descriptor it will trigger a use-after-free and if the file
descriptor is closed (latest when the application exits) a double-free is
triggered.
anon_inode_getfd() performs 3 tasks, allocate a file struct, allocate a
file descriptor for the current process and install the file struct in the
file descriptor. As soon as the file struct is installed in the file
descriptor it is accessible by userspace (even if the IOCTL itself hasn't
completed yet), this means uninstalling the fd on the error path is not an
option, since userspace might already got a reference to the file.
Instead anon_inode_getfd() needs to be broken into its individual steps.
The allocation of the file struct and file descriptor is done first, then
the copy_to_user() is executed and only if it succeeds the file is
installed.
Since the file struct is reference counted it can not be just freed, but
its reference needs to be dropped, which will also call the release()
callback, which will free the state attached to the file. So in this case
the normal error cleanup path should not be taken.

This code was breaking playback when we have both playback and capture

doesn't include the necessary header. Fix the build
break caused by that, by simply including the
missing header.

This inline function is unused on configurations
where dma_map/unmap are empty macros.
Make the function inline to avoid gcc errors because
of an unused static function.
