This patch is part of the cleanup of the HID drivers
against their low-level transport layer.
With new touchscreens relying on I2C, it's better to
handle now these dependencies before users get kernel oopses.

HID: use hid_hw_wait() instead of direct call to usbhid
This removes most of the dependencies between hid drivers and usbhid.
The patch was constructed by replacing all occurences of
usbhid_wait_io() by its hid_hw_wait() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.
As of today, few drivers are still requiring an explicit USB layer
dependency:
* ntrig (a patch is on its way)
* multitouch (one patch following and another on its way)
* lenovo tpkbd
* roccat
* sony
The last three are two deeply using direct calls to the usb subsystem
to be able to be cleaned right now.

drivers/rtc/rtc-tps65910.c: set irq flag to IRQF_EARLY_RESUME during irq request
All interrupt get disabled during system suspend and enabled during system
resume. The enabling/disabling of interrupt happen in sequence of
interrupt registration with framework.
Therefore, in resume, the parent interrupt of this device enabled before
the RTC irq interrupt enabled. If RTC is enabled for alarm wake and if
system wake by alarm then there is interrupt pending for RTC. In resume,
the parent interrupt get enabled before the rtc interrupt and hence ISR
get served. In ISR, it founds that rtc interrupt is disabled and so it
does not call the rtc isr handler and hence it misses the interrupt.
Setting flag for early resume so that rtc interrupt get enabled before
parent interrupt and so rtc interrupt get enabled when parent interrupt
handler check for interrupt of device and call the rtc handler if it is
there. This way it will not miss the interrupt.

initialization. But new device of LP855x family, LP8557 has different
register map and initialization sequence. To support new device
architecture, initialization process should be changed.

=============================================
With lp855x_device_config, device specific features are configurable.
Use configurable function calls and register addresses rather than fixed values.
Change on device initialization
===============================
In old LP855x driver architecture, the device initialization was simple.
- Just update the brightness/device control register/ROM area(optional).
In new LP855x driver architecture, two more works are added - pre_init and
post_init.
Those init functions are optional, used for new device LP8557.
New device initialization flow: generic sequence
=================================================
1) pre_init_device()
2) update the brightness register
3) update the device control register
4) update ROM area if need
5) post_init_device()
Name change

spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we

'before_power' was used to check the previous status when resume() is
called. However, FB_BLANK_POWERDOWN was used in suspend() all the time,
so there is no need to check the previous status. Also, redundant return
variables are removed to reduce the code.
