Near the beginning of w1_attach_slave_device() we increment a w1 master
reference count.
Later, when we are going to exit this function without actually attaching
a slave device (due to failure of __w1_attach_slave_device()) we need to
decrement this reference count back.

This adds a driver for a DS2405 1-wire single-channel addressable switch.
The DS2405 can also work as a single-channel binary remote sensor.
This driver supports two attributes: "state" and "output" which are the
same attribute names as supported by existing DS2406, DS2408 and DS2413
drivers.

ds2490 driver was doing USB transfers from / to buffers on a stack.
This is not permitted and made the driver non-working with vmapped stacks.
Since all these transfers are done under the same bus_mutex lock we can
simply use shared buffers in a device private structure for two most common
of them.
While we are at it, let's also fix a comparison between int and size_t in
ds9490r_search() which made the driver spin in this function if state
register get requests were failing.

In case of error returned by '_omap_hdq_reset()', free resources as done

This patch slighly changes the semantic of the code. It now propagates the

When using the ETM4x tracers from the perf interface two trace options are
available: cycle accurate and timestamp.
Enabling the timestamp feature is done by setting TRCCONFIGR.TS (bit 11).
The position of the timestamp bit in that register coincidentally happens
to be the same as what was chosen to enable timestamping from the 'mode'
sysFS entry. The code does the right thing but the semantic is wrong.
This patch sets TRCCONFIGR.TS explicitly, as it is done from the sysFS
interface. That way timestamps are set the same way from both perf and
sysFS and there is no misunderstanding as to what is intended.

Commit d52c9750f150 ("coresight: reset "enable_sink" flag when need be")
caused a kernel panic because of the using of an invalid value: after
'for_each_cpu(cpu, mask)', value of local variable 'cpu' become invalid,
causes following 'cpu_to_node' access invalid memory area.
This patch brings the deleted 'cpu = cpumask_first(mask)' back.

Commit 050c3d52cc7810d9d17b8cd231708609af6876ae ("vme: make core
vme support explicitly non-modular") dropped the remove function
because it appeared as if it was for removal of the bus, which is
not supported.
However, vme_bus_remove() is called when a VME device is removed
from the bus and not when the bus is removed; as it calls the VME
device driver's cleanup function. Without this function, the
remove() in the VME device driver is never called and VME device
drivers cannot be reloaded again.
Here we restore the remove function that was deleted in that
commit, and the reference to the function in the bus structure.

Chanwoo writes:
Update extcon for 4.11
Detailed description for this pull request:
1. Add the new extcon driver.
- Intel INT3496 ACPI USB id detection driver detects whether
EXTCON_USB_HOST is attached or detached. (extcon-intel-int3496.c)
2. Add the new type of external connector.
- EXTCON_CHG_USB_PD (USB Power Delivery) provides the increased
power more than 7.5W to device with larger power demand.
3. Add the description for EXTCON_CHG_USB_(SDP|ACA|SLOW|FAST)
- EXTCON_CHG_USB_SDP should always appear together with EXTCON_USB
- EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST.
- EXTCON_CHG_USB_SLOW can provide at least 500mA of current at 5V
- EXTCON_CHG_USB_FAST can provide at least 1A of current at 5V.
4. Modify the connector name of EXTCON_USB_HOST
- "USB_HOST" -> "USB-HOST"
5. Update the extcon core
- Move the private extcon structure into driver/extcon directory.
The 'struct extcon_dev' should be only handled by extcon core
to prevent the direct access and to maintain the integrity of it.
- Remove the ambigous operation of extcon_register_notifier()
in case of the 'extcon_dev' instance is NULL. The user of
extcon_register_notifier() have to specify the correct instance
of the provider extcon driver.
6. Update the extcon drivers and fix the minor issues
- Update the extcon-axp288 driver to remove the unncessary code.
- Add pinctrl operation during suspend mode to extcon-usb-gpio driver.
- Clean up the extcon-arizona/adc-jack driver.
- Use the dev_dbg() for debug messsage on extcon-palmas driver.
- Return the error code on failure of extcon_sync()

After the latest change to make sure the compiler actually does a memset,
it is now smart enough to flag the stack overflow at compile time,
at least with gcc-7.0:
drivers/misc/lkdtm_bugs.c: In function 'lkdtm_CORRUPT_STACK':
drivers/misc/lkdtm_bugs.c:88:144: warning: 'memset' writing 64 bytes into a region of size 8 overflows the destination [-Wstringop-overflow=]
To outsmart the compiler again, this moves the memset into a noinline
function where (for now) it doesn't see that we intentionally write
broken code here.

The stm is automatically enabled when an application sets the policy
via ->link() call back by using coresight_enable(), which keeps the
refcount of the current users of the STM. However, the unlink() callback
issues stm_disable() directly, which leaves the STM turned off, without
the coresight layer knowing about it. This prevents any further uses
of the STM hardware as the coresight layer still thinks the STM is
turned on and doesn't enable the hardware when required. Even manually
enabling the STM via sysfs can't really enable the hw.
e.g,
$ echo 1 > $CS_DEVS/$ETR/enable_sink
$ mkdir -p $CONFIG_FS/stp-policy/$source.0/stm_test/

This driver provides an access to EEPROM of IDT PCIe-switches. IDT PCIe-
switches expose a simple SMBus interface to perform IO-operations from/to
EEPROM, which is located at private (so called Master) SMBus. The driver
creates a simple binary sysfs-file to have an access to the EEPROM using
the SMBus-slave interface in the i2c-device susfs-directory:
/sys/bus/i2c/devices/<bus>-<devaddr>/eeprom
In case if read-only flag is specified at dts-node of the device, User-space
applications won't be able to write to the EEPROM sysfs-node.
Additionally IDT 89HPESx SMBus interface has an ability to read/write
values of device CSRs. This driver exposes debugfs-file to perform simple
IO-operations using that ability for just basic debug purpose. Particularly
the next file is created in the specific debugfs-directory:
/sys/kernel/debug/idt_csr/
Format of the debugfs-file value is:
$ cat /sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>;
<CSR address>:<CSR value>
So reading the content of the file gives current CSR address and it value.
If User-space application wishes to change current CSR address, it can just
write a proper value to the sysfs-file:
$ echo "<CSR address>" >
/sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>
If it wants to change the CSR value as well, the format of the write
operation is:
$ echo "<CSR address>:<CSR value>" > \
/sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>;
CSR address and value can be any of hexadecimal, decimal or octal format.

Pull namespace fixes from Eric Biederman:
"This tree contains 4 fixes.
The first is a fix for a race that can causes oopses under the right
circumstances, and that someone just recently encountered.
Past that are several small trivial correct fixes. A real issue that
was blocking development of an out of tree driver, but does not appear
to have caused any actual problems for in-tree code. A potential
deadlock that was reported by lockdep. And a deadlock people have
experienced and took the time to track down caused by a cleanup that
removed the code to drop a reference count"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
sysctl: Drop reference added by grab_header in proc_sys_readdir
pid: fix lockdep deadlock warning due to ucount_lock
libfs: Modify mount_pseudo_xattr to be clear it is not a userspace mount
mnt: Protect the mountpoint hashtable with mount_lock

Pull driver core fix from Greg KH:

Pull USB fixes from Greg KH:
"Here are a few small USB driver fixes for 4.10-rc4 to resolve some
reported issues.
The "largest" here is a number of bugs being fixed in the ch341
usb-serial driver, to hopefully resolve the mess of different devices
floating around that use this driver that have been having problems
with the 4.10-rc1 release.
There's also a tiny musb fix that I missed in the last pull request,
as well as the traditional xhci fix rounding out the batch.
All have been in linux-next with no reported issues"
