Wacom driver cleanups from Gustavo A. R. Silva and Jason Gerecke
Support for Pro Pen slim from Jason Gerecke

Wacom has introduced a new pen compatible with its MobileStudio Pro and
other tablets. Although adding it to the tool ID tablet is not strictly
necessary unrecognized pens are reported as BTN_TOOL_PEN already, unless
the tablet sends the "eraser" bit, when BTN_TOOL_RUBBER is used instead),
we'll keep it updated anyway.

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/hid/wacom_wac.c: In function ‘wacom_setup_pen_input_capabilities’:
drivers/hid/wacom_wac.c:3506:3: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

The 'wacom_hid_usage_quirk' function is the intended home for fixing
up descriptors that are buggy or that don't quite fit the mold. Commit
578325120e was supposed to move all of these quirks but it missed the
code to handle fixup the serial number usages for AES pens. Lets move
this code out of 'wacom_wac_pen_usage_mapping' where it was previously
lurking and put it into the same place as the others.

Instead of using an 128-byte on-stack array to store the request, we can
instantiate the request on stack directly. This can save the stack usage of
these functions, since most of the requests are much smaller than 128 bytes.

Currently we are using one additional static variable and a spinlock to
prevent contention of writing IPC messages to ISH hardware, which is
not necessary. Once ISH is ready to accept new data, we can push new
data to hardware. This pushing of new data is already protected by
wr_processing_spinlock for contention, which is enough. So use this
spinlock to check both readiness for accepting new data and once ready
allow writing of ipc message from queue to ISH hardware.
While here, cleaned up some space after return.

When performing a warm reset in ishtp bus driver, the ishtp_cl_device
will not be removed, its fw_client still points to the already freed
ishtp_device.fw_clients array.
Later after driver finishing ishtp client enumeration, this dangling
pointer may cause driver to bind the wrong ishtp_cl_device to the new
client, causing wrong callback to be called for messages intended for
the new client.
This helps in development of firmware where frequent switching of
firmwares is required without Linux reboot.

While using Elan touchpads, the message floods:
[ 136.138487] i2c_hid i2c-DELL08D6:00: i2c_hid_get_input: incomplete report (14/65535)
Though the message flood is annoying, the device it self works without
any issue. I suspect that the device in question takes too much time to
pull the IRQ back to high after I2C host has done reading its data.
Since the host receives all useful data, let's ignore the input report
when there's no data.

The Intel ISH HID can now have other devices attached to it, not just
sensors. Hence ISH HID transport is no longer just used for sensors.
Currently the vendor and product id is hardcoded for sensors, but they
can be obtained from ISH firmware for the real device. The driver already
extract them and store as part of device_info structure in client_data.
So use vendor id/product id obtained from the ISH firmware.

busy_clear bit
Host driver should handle interrupt mask register earlier than wake up ish FW
else there will be conditions when FW interrupt comes, host PIMR register still
not set ready, so move the interrupt mask setting before ish_wakeup.
Clear PISR busy_clear bit in ish_irq_handler. If not clear, there will be
conditions host driver received a busy_clear interrupt (before the busy_clear
mask bit is ready), it will return IRQ_NONE after check_generated_interrupt,
the interrupt will never be cleared, causing the DEVICE not sending following
IRQ.
Since PISR clear should not be called for the CHV device we do this change.
After the change, both ISH2HOST interrupt and busy_clear interrupt will be
considered as interrupt from ISH, busy_clear interrupt will return IRQ_HANDLED
from IPC_IS_BUSY check.

Toshiba WT10A tablet bluetooth keyboard support from Hans de Goede

The bluetooth-keyboard which comes with the Toshiba WT10A tablet uses
a couple of usage codes in the vendor specific ffbc page.
The keyboard has a vendor-id of 04f2 which maps to Chicony.
Other then adding a few keymappings for the ffbc usages, no special
handling is necessary. So rather then adding a new hid-toshiba driver,
this commit adds the ID and 2 extra key-mappings to the hid-topseed
driver. The hid-topseed driver already contains mapping for some
ffbc usages (and does nothing else) and it already binds to another
Chicony manufactured keyboard.

Rumble support on SHANWAN PS3 gamepad is not working when a user
program has asked it to. If a HID Output Reports is sent via Control
Channel then it will be discard by gamepad, thus rumble motor and led
settings in Output Report are ignored.
This patch therefore sends HID Output Report via Interrupt Channel to
SHANWAN gamepad instead of Control Channel, fixing rumble motor and
led settings.
