Currently, we're probing r/w registers at probe time.
This is potentially dangerous, probe some read only registers instead.

ac3d5bfecc V4L/DVB (11451): gspca - m5602-s5k83a: Add rotation, ctrl cache. Rename some ctrls.
s5k83a sensor mounted on many acer laptops have a swiwel allowing it to be rotated. When the camera is in its rotated state, the image needs to be flipped. The only way to check for if the camera has been flipped is to continously poll a register in the m5602. This patch creates a kernel thread which does this. This patch renames some v4l2 ctrls and finally implements a cache in order to prevent unnecessary sensor reads.

0ccad87012 atmel_serial: fix hang in set_termios when crtscts is enabled
After enabling hardware flow control, any subsequent termios call may hang
waiting for the transmitter to drain.  This appears to be caused by a
busy-loop in set_termios() waiting for the transmitter to become empty,
which may take a very long time (or hang indefinitely) if the device at
the other end is blocking us.

A quick look through the tty and serial_core code indicates that any
necessary flushing (which is optional) has already been done at this
point, so there's no need for the driver to flush the transmitter on its
own.

Fix it by removing the busy-loop altogether.

1aa4bed82a tty: fix sanity check
The WARN_ON() that was added to tty_reopen can be triggered in the specific
case of a hangup occurring during a re-open of a tty which is not in the
middle of being otherwise closed.

In that case however the WARN() is bogus as we don't hold the neccessary
locks to make a correct decision.

The case we should be checking is "if the ldisc is not changing and reopen
is occuring". We could drop the WARN_ON but for the moment the debug is more
valuable even if it means taking a mutex as it will find any other cases.

the current 3270 view is deactivated and for non-console 3270 device
the release callback is done. This disconnects the current tty /

If the system panics before the 3270 device has been resumed, the ccw

0259162ecd [S390] pm: hvc_iucv power management callbacks
The patch adds supporting for suspending and resuming IUCV HVC terminal
devices from disk. The obligatory Linux device driver interfaces has
been added by registering a device driver on the IUCV bus.
For each IUCV HVC terminal device the driver creates a respective device
on the IUCV bus.

To support suspend and resume, the PM freeze callback severs any established
IUCV communication path and triggers a HVC tty hang-up when the system image
is restored.
IUCV communication path are no longer valid when the z/VM guest is halted.

The device driver initialization has been updated to register devices and
the a new routine has been extracted to facilitate the hang-up of IUCV HVC
terminal devices.

about suspend/resume even if netiucv is the only loaded iucv-exploting
module without any real net_device defined.

The PM freeze callback closes all open netiucv connections. Thus the
corresponding iucv path is removed.
The PM thaw/restore callback re-opens previously closed netiucv
connections.

62b7494209 [S390] pm: power management support for SCLP drivers.
The SCLP base driver defines a new notifier call back for all upper level SCLP
drivers, like the SCLP console, etc. This guarantees that in suspend first the
upper level drivers are suspended and afterwards the SCLP base driver. For
resume it is the other way round. The SCLP base driver itself registers a
new platform device at the platform bus and gets PM notifications via
the dev_pm_ops.

In suspend, the SCLP base driver switches off the receiver and sender mask
This is done in sclp_deactivate(). After suspend all new requests will be
rejected with -EIO and no more interrupts will be received, because the masks
are switched off. For resume the sender and receiver masks are reset in
the sclp_reactivate() function.

When the SCLP console is suspended, all new messages are cached in the
sclp console buffers. In resume, all the cached messages are written to the
console. In addition to that we have an early resume function that removes
the cached messages from the suspend image.

pm_notifier_callchain is used to get control on PM events. Since watchdog
operation and suspend cannot work together in a reliable fashion, the open

the console buffer is flushed to the 3215 device to have an empty console

push out the oldest messages to make room for the most recent message.
On resume the buffered messages are printed. If the system panics before

The legacy i2c binding model is going away soon, so convert the
macintosh windfarm drivers to the new model or they will break.

1b9f37d488 therm_pm72: Convert to a new-style i2c driver
The legacy i2c binding model is going away soon, so convert the
macintosh therm_pm72 driver to the new model or it will break.

This is really a quick and dirty conversion, that should do the trick
for now, but no doubt that something cleaner can be done if anyone is
interested.

a231591f04 i2c-viapro: Add new PCI device ID for VX855
The south bridge of the VIA VX855 chipset has a different PCI Device ID
so i2c-viapro.c needs to be updated with this.

4b364f230a i2c/chips: Move max6875 to drivers/misc/eeprom
This driver only reads the user EEPROM of that chip, so we can move it
to the eeprom-directory in order to further clean up (and later remove)
drivers/i2c/chips.

The Kconfig text was updated to match the current functionality,
dropping the meanwhile obsoleted parts.

Defconfigs have been adapted.

c52cf01f5b i2c: Do not give adapters a default parent
We don't need to give adapters a parent if they don't have one. The
driver core will put them in the virtual device directory and all will
be fine.

fa1b2ca4fa i2c: Do not probe for TV chips on Voodoo3 adapters
There's no point in giving the I2C bus of Voodoo3 adapters a class
value, there's no video chip driver checking for it anymore. If
support is ever needed, the video device should be instantiated
explicitly rather than probed.

To the best of my knowledge the only video chip that can be found on
these boards is a BT869 video encoder, for which no support exists
currently.

Thanks, but it turns out I hit a 32 bit integer overflow in
the gain calculation. I'd like to mend that with the following
patch. Now max_uV could be increased up to 4.294 V, enough to
charge LiPo cells.

b110a8fb24 regulator/max1586: support increased V3 voltage range
The V3 regulator can be configured with an external resistor
connected to the feedback pin (R24 in the data sheet) to
increase the voltage range.

For example, hx4700 has R24 = 3.32 kOhm to achieve a maximum
V3 voltage of 1.55 V which is needed for 624 MHz CPU frequency.
