6b91f2d42a mmc: sdhci-pci: remove PCI PM functions in suspend/resume callback
It is not required (in fact it even is not recommended) that a PCI
driver's suspend() callback save the standard configuration registers
of the device, prepare it for waking up the system, or put it into a
low-power state.  All of these operations can very well be taken
care of by the PCI subsystem, without the driver's participation. Thus
remove these PCI functions.

For the device which has wake up capability, use device_init_wakeup to
init the wake up capability so that PCI core will help to enable the wakeup
for it.

5204d00f06 mmc: Do not advertise secure discard if it is blacklisted
Currently when the device secure discard implementation is
blacklisted (MMC_QUIRK_SEC_ERASE_TRIM_BROKEN quirk is set)
instead of secure discard we're going to do normal discard,
which is wrong.

When the secure discard is known to be broken we should just
disallow it entirely and not advertise this functionality to
the user. Fix it.

Also move mmc_fixup_device() in from of mmc_blk_alloc() so we
can get quirks set before we attempt to set queue information.

2a7e19af94 e1000e: Fix Runtime PM blocks EEE link negotiation in S5
Adding a function, and associated calls, to flush writes to (read) the LPIC
MAC register before entering the shutdown flow.  This fixes the problem
of the PHY never negotiating a 100M link (if both sides of the link support
EEE and 100M link) when Runtime PM is enabled.

2116bc25e8 e1000e: Fix EEE in S5 w/ Runtime PM enabled
The process of shutting down the system causes a call to the close PM
callback.  The reset in close causes a loss of link, and the resultant
LSC interrupt causes the Runtime PM idle callback to be called.  The
check for link (while link is down) in the idle callback is wiping the
information about the EEE ability of the link partner.  The information is
still gone when the PHY is powered back up in the shutdown flow.  This
causes EEE in S5 to fail when Runtime PM is active.

Save the link partner's EEE ability in the idle callback so that a Runtime
PM event will not cause a loss of this information.

b4c1e6bf1c e1000e: Add support for EEE in Sx states
On I217 and newer hardware, EEE is enabled in the PHY by the software
when link is up and disabled by the hardware when link is lost.

To enable EEE in Sx (When both ends of the link support, and are enabled
for, EEE and 100Mbps), we need to disable LPLU and configure the PHY to
automatically enable EEE when link is up, since there will be no software
to complete the task.

To configure this in the PHY, the Auto Enable LPI bit in the Low Power
Idle GPIO Control register must be set.  For normal operation in S0, this
bit must be cleared.

356237d67a [media] ati_remote: Better default keycodes
This tries to make them more like other remotes, and/or
the button labels.

Notably, the (>>) button is made KEY_FASTFORWARD, which is the
correct opposite of (<<)'s KEY_REVERSE.  (It was KEY_FORWARD,
something else entirely.)

Likewise, KEY_STOP is the Sun keyboard "interrupt program" key;
the media key is KEY_STOPCD.

A restriction is that I try to avoid keycodes above 255, as the X11
client/server protocol is limited to 8-bit key codes.  If not for
this, I would have used the KEY_NUMERIC_x codes for the numbers.

7cec72ce00 [media] rc-core: don't use dynamic_pr_debug for IR_dprintk()
The hole point of IR_dprintk() is that, once a level is
given at debug parameter, all enabled IR parsers will show their
debug messages.

While converting it to dynamic_printk might be a good idea,
right now it just makes very hard to debug the drivers, as
one needs to both pass debug=1 or debug=2 to rc-core and
to use the dynamic printk to enable all the desired lines.

That doesn't make sense!

So, revert to the old way, as a single line is changed,
and the debug parameter will now work as expected.

acb1ce223b ixgbe: Correct X540 semaphore error
In the function ixgbe_get_swfw_sync_semaphore, an incorrect

to manipulating the IXGBE_SWFW_SYNC register without holding

if getting the REGSMP bit in the IXGBE_SW_FW_SYNC register
timed out, no error code would be returned, making the caller
think that it had successfully acquired the lock. Fix both of
those issues and clean up the function a bit, such as make the

- Reports the current status of the battery (discharging, charging, full).
- Also notify the upower daemon when there is a change in the battery
  value.
- keep the battery value as a percentage, not the raw value
- add WACOM_QUIRK_BATTERY to easily add a battery to a device (required
  for Bluetooth devices)

c757cbafd6 Input: wacom - put a flag when the led are initialized
This solves a bug with the wireless receiver:
- at plug, the wireless receiver does not know which Wacom device it is
  connected to, so it does not actually creates all the LEDs
- when the tablet connects, wacom->wacom_wac.features.type is set to the
  proper device so that wacom_wac can understand the packets
- when the receiver is unplugged, it detects that a LED should have been
  created (based on wacom->wacom_wac.features.type) and tries to remove
  it: crash when removing the sysfs group.

Side effect, we can now safely call several times wacom_destroy_leds().

80befa9381 Input: wacom - remove field pktlen declaration in the list of devices
pktlen is now overwritten by the driver directly by reading the hid
report descriptor. There is no need to declare it statically.
We also move down the position of the field in the struct so that
we can keep the current declaration of Wacom devices.

HID already parses the report descriptor, so use it instead of implementing
our own.  The special case for Bamboo PT 3rd gen is also removed and
handled in the same way Intuos 5 is treated, by hardcoding it in the
driver.  Last, the unit_exponent stored into the hid field already is
signed, so there is no need to handle a two's complement anymore.

4451e088cf Input: wacom - remove usb dependency for siblings devices
Wacom tablets can share different physical sensors on one physical device.
These are called siblings in the code. The current way of implementation
relies on the USB topology to be able to share data amongs those sensors.

We can replace the code to match a HID subsystem, without involving the USB
topology:
- the first probed sensor does not find any siblings in the list
  wacom_udev_list, so it creates its own wacom_hdev_data with its own
  struct hid_device
- the other sensor checks the current list of siblings in wacom_hdev_data,
  and if there is a match, it associates itself to the matched device.

To be sure that we are not associating different sensors from different
physical devices, we also check for the phys path of the hid device which
contains the USB topology.

Matches the current behavior of the HID subsystem and removes one more
dependency over USB.

The current user space clients which relies on this to fetch the
LEDs path need an update. However, we already break them in the
kernel v3.11 for the Bluetooth Wacom devices. They are going to be fixed
soon.

c31a408f7a Input: wacom - install LED/OLED sysfs files in the HID device instead of USB
Removes one more dependency over USB, but requires some changes in
the user space to find the sysfs files correctly.

This patch breaks the user space. However, the number of program
accessing the LEDs is quite limited and we can easily patch them
to handle the new HID behavior.
