sfc: Use 64-bit writes for TX push where possible

However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:
1. The function will needlessly bail out without decrementing back the
runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
negative. This means that wl1271_power_on will continue even if
wl1271_sdio_power_on bailed out. As a result, sdio transactions will

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:
1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
since the device was not necessarily booted by the time the function
is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
locked and the nvs member will become a dangling pointer.

current handler: serial idle
...
and the reason is that setting IRQF_ONESHOT will now result in those
interrupt handlers having different IRQF flags, and thus being
unsharable. So the commit log in the reverted commit:
"Since it is required for those users and
there is no difference for others it makes sense to add this flag
unconditionally."
is simply not true: there may not be any difference from a "actions at
irq time", but there is a *big* difference wrt this flag testing irq
management (see __setup_irq() in kernel/irq/manage.c).
One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but
right now the safe course of action is to revert the change. Let's
revisit this in a later merge window.

Toshiba Satellite L300D with ATI Mobility Radeon X1100 sends data

HID: wiimote: Add status and return request handlers
The wiimote resets the current drm when an extension is plugged in.
Fortunately, it also sends a status report in this situation so we just
reset the drm on every status report to keep the drm consistent.
Also handle return reports from the wiimote which indicate success and
failure of requests that we've sent.

HID: wiimote: Add drm request
The wiimote reports data in several data reporting modes (DRM). The DRM
request makes the wiimote send data in the requested drm.
The DRM mode can be set explicitely or can be chosen by the driver. To let
the driver choose the DRM mode, pass WIIPROTO_REQ_NULL placeholder to it. This
is no valid request and is replaced with an appropriate DRM.
Currently, the driver always sets the basic DRM_K mode, but this will be
extended when further peripherals like accelerometer and IR are supported.

HID: usbhid: Add support for SiGma Micro chip
Patch to add SiGma Micro-based keyboards (1c4f:0002) to hid-quirks.
These keyboards dont seem to allow the records to be initialized, and hence a
timeout occurs when the usbhid driver attempts to initialize them. The patch
just adds the signature for these keyboards to the hid-quirks list with the
setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the
timeout to occur.

ath9k_hw: Fix STA (AR9485) bringup issue due to incorrect MAC address
Due to some recent optimization done in the way the mac address
bytes are written into the OTP memory, some AR9485 chipsets were
forced to use the first byte from the eeprom template and the
remaining bytes are read from OTP.
AR9485 happens to use generic eeprom template which has 0x1 as
the first byte causes issues in bringing up the card.
So fixed the eeprom template accordingly to address the issue.

Input: ad714x - read the interrupt status registers in a row
The interrupt status registers should be read in row to avoid invalid data.
Alter "read" method for both bus options to allow reading several registers
in a row and make sure we read interrupt status registers properly.
Read sequence saves 50% of bus transactions compared to single register
reads. So use it also for the result registers, which are also located
in a row.
Also update copyright notice.
