at91: at91-ohci: configure overcurrent pins as input GPIOs
As a new overcurrent_pin[] array has been added to the at91_usbh_data
structure, those pins must be muxed to work properly. This commit
implements this muxing for all AT91 SoCs that support the AT91 OHCI.

at91: at91-ohci: support overcurrent notification
Several USB power switches (AIC1526 or MIC2026) have a digital output
that is used to notify that an overcurrent situation is taking
place. This digital outputs are typically connected to GPIO inputs of
the processor and can be used to be notified of those overcurrent
situations.
Therefore, we add a new overcurrent_pin[] array in the at91_usbh_data
structure so that boards can tell the AT91 OHCI driver which pins are
used for the overcurrent notification, and an overcurrent_supported
boolean to tell the driver whether overcurrent is supported or not.
The code has been largely borrowed from ohci-da8xx.c and
ohci-s3c2410.c.

The existing OHCI AT91 driver made the assumption that the enable
input of the USB power switch was active low. However, some USB power
switches such as the Micrel MIC2026-1 [1] have an active high input to
enable the power. A new vbus_pin_inverted attribute is added to the
at91_usbh_data structure so that board files can tell the OHCI driver
if the vbus pin logic is active low or active high.

HID: wacom: Unregister sysfs attributes on remove
HID devices can be hotplugged so we should unregister all sysfs attributes when
removing a driver. Otherwise, manually unloading the wacom-driver will not
remove the sysfs attributes. Only when the device is disconnected, they are

HID: wacom: Fix error path of power-supply initialization
power_supply_unregister() must not be called if power_supply_register() failed.
The wdata->psy.dev pointer may point to invalid memory after a failed
power_supply_register() and hence wacom_remove() will fail while calling
power_supply_unregister().
This changes the wacom_probe function to fail if it cannot register the
power_supply devices. If we would want to keep the previous behaviour we had to
keep some flag about the power_supply state and check it on wacom_remove, but
this seems inappropriate here. Hence, we simply fail, too, if
power_supply_register fails.

i2c-tegra: fix possible race condition after tx
In tegra_i2c_fill_tx_fifo, once we have finished pushing all the bytes
to the I2C hardware controller, the interrupt might happen before we
have updated i2c_dev->msg_buf_remaining at the end of the function.
Then, in tegra_i2c_isr, we will call again tegra_i2c_fill_tx_fifo
triggering weird behaviour. This has been shown to happen under real
conditions.
