9e50108668 mfd: Add initial WM8994 support
The WM8994 is a highly integrated ultra low power audio hub CODEC.
Since it includes on-board regulators and GPIOs it is represented
as a multi-function device, though the overwhelming majority of
the functionality is provided by the ASoC CODEC driver.

The TWL4030_BCI_BATTERY config option originates from a patch to the

the functionality nears inclusion under a different name so this

external cables being connected, voltages on batteries dropping

6048a3dd23 mfd: Add HTCPLD driver
This change introduces a driver for the HTC PLD chip found
on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.
Specifically:

 * it can have several sub-devices, each with its own I2C
   address
 * Each sub-device provides 8 output and 8 input pins
 * The chip attaches to one GPIO to signal when any of the
   input GPIOs change -- at which point all chips must be
   scanned for changes

This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework.  This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.

53dbab7af9 mfd: Support 88pm8606 in 860x driver
88PM8606 and 88PM8607 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according to
requirement.

There's some logic tightly linked between these two chips. For example, USB
charger driver needs to access both chips by I2C interface.

Now share one driver to these two devices. Only one I2C client is identified
in platform init data. If another chip is also used, user should mark it in
companion_addr field of platform init data. Then driver could create another
I2C client for the companion chip.

All I2C operations are accessed by 860x-i2c driver. In order to support both
I2C client address, the read/write API is changed in below.

reg_read(client, offset)
reg_write(client, offset, data)

The benefit is that client drivers only need one kind of read/write API. I2C
and MFD driver can be shared in both 8606 and 8607.

Since API is changed, update API in 8607 regulator driver.

0e820ab601 mfd: Correct use after free for t7l66xb
The structure t7l66xb should not be freed before the subsequent references
to its fields in the arguments to clk_put.  Furthermore, this structure is
allocated near the beginning of the function, and a goto to the label
err_noirq appears after a successful allocation, so it would seem that the
kfree should be moved down below this label.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

b8fa05719b Revert "lib: build list_sort() only if needed"
This reverts commit a069c266ae.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.

7bc80cd935 usbfs: fix deadlock on 'usbfs_mutex', clean up poll
The caller of usbfs_conn_disc_event() in some cases (but not always)
already holds usbfs_mutex, so trying to protect the event counter with
that lock causes nasty deadlocks.

The problem was introduced by commit 554f76962d ("USB: Remove BKL from
poll()") when the BLK protection was turned into using the mutex instead.

So fix this by using an atomic variable instead.  And while we're at it,
get rid of the atrocious naming of said variable and the waitqueue it is
associated with.

This also cleans up the unnecessary locking in the poll routine, since
the whole point of how the pollwait table works is that you can just add
yourself to the waiting list, and then check the condition you're
waiting for afterwards - avoiding all races.

It also gets rid of the unnecessary dynamic allocation of the device
status that just contained a single word.  We should use f_version for
this, as Dmitry Torokhov points out.  That simplifies everything
further.

a8a5164c29 gpio: cs5535-gpio: fix input direction
The cs5535-gpio driver's get() function was returning the output value.
This means that the GPIO pins would never work as an input, even if
configured as an input.

The driver should return the READ_BACK value, which is the sensed line
value.  To make that work when the direction is 'output', INPUT_ENABLE
needs to be set.

In addition, the driver was not disabling OUTPUT_ENABLE when the direction
is set to 'input'.  That would cause the GPIO to continue to drive the pin
if the direction was ever set to output.

This issue was noticed when attempting to use the gpiolib driver to read
an external input.  I had previously been using the char/cs5535-gpio
driver.
