HID: ignore Petzl USB headlamp

2017-08-07T01:59:49+00:00

[ Upstream commit 08f9572671c8047e7234cbf150869aa3c3d59a97 ]

This headlamp contains a dummy HID descriptor which pretends to be
a mouse-like device, but can't be used as a mouse at all.

HID: i2c-hid: Add sleep between POWER ON and RESET

2017-07-05T12:40:24+00:00

[ Upstream commit a89af4abdf9b353cdd6f61afc0eaaac403304873 ]

Support for the Asus Touchpad was recently added. It turns out this
device can fail initialisation (and become unusable) when the RESET
command is sent too soon after the POWER ON command.

Unfortunately the i2c-hid specification does not specify the need for
a delay between these two commands. But it was discovered the Windows
driver has a 1ms delay.

As a result, this patch modifies the i2c-hid module to add a sleep
inbetween the POWER ON and RESET commands which lasts between 1ms and 5ms.

See https://github.com/vlasenko/hid-asus-dkms/issues/24 for further
details.

HID: wacom: Have wacom_tpc_irq guard against possible NULL dereference

2017-06-07T10:07:47+00:00

commit 2ac97f0f6654da14312d125005c77a6010e0ea38 upstream.

The following Smatch complaint was generated in response to commit
2a6cdbd ("HID: wacom: Introduce new 'touch_input' device"):

    drivers/hid/wacom_wac.c:1586 wacom_tpc_irq()
             error: we previously assumed 'wacom->touch_input' could be null (see line 1577)

The 'touch_input' and 'pen_input' variables point to the 'struct input_dev'
used for relaying touch and pen events to userspace, respectively. If a
device does not have a touch interface or pen interface, the associated
input variable is NULL. The 'wacom_tpc_irq()' function is responsible for
forwarding input reports to a more-specific IRQ handler function. An
unknown report could theoretically be mistaken as e.g. a touch report
on a device which does not have a touch interface. This can be prevented
by only calling the pen/touch functions are called when the pen/touch
pointers are valid.

HID: wacom: don't apply generic settings to old devices

2017-04-12T10:41:21+00:00

[ Upstream commit e7deb1570a527d3c74be4e21a72b1b459605c501 ]

Non-generic devices have numbered_buttons set for both pen and
touch interfaces by default. The actual number of buttons on the
interface is normally manually decided later, which is different
from what those HID generic devices are processed, where number
of buttons are directly retrieved from HID descriptors.

This patch adds the missed HID_GENERIC check and moves the statement
to wacom_setup_pad_input_capabilities since it's not a quirk anymore.

HID: usbhid: Add quirk for Mayflash/Dragonrise DolphinBar.

2017-04-12T10:41:18+00:00

[ Upstream commit 8aa2cc7e747881d1fd52db28261b201d4e3e5565 ]

The DolphinBar by Mayflash (identified as Dragonrise) needs
HID_QUIRK_MULTI_INPUT to split it up into four input devices. Without this
quirk the adapter is falsely recognized as a tablet. See also bug 115841

HID: multitouch: do not retrieve all reports for all devices

2017-04-12T10:41:16+00:00

[ Upstream commit b897f6db3ae2cd9a42377f8b1865450f34ceff0e ]

We already have in place a quirk for Windows 8 devices, but it looks
like the Surface Cover are not conforming to it.
Given that we are only interested in 3 feature reports (the ones that
the Windows driver retrieves), we should be safe to unconditionally apply
the quirk to everybody.

In case there is an issue with a controller, we can always mark it as such
in the transport driver, and hid-multitouch won't try to retrieve the
feature report.

HID: multitouch: enable the Surface 3 Type Cover to report multitouch data

2017-04-12T10:41:16+00:00

[ Upstream commit 8fe89ef076fa104f514da6ef61d90f5bf93488e3 ]

There is no reasons to filter out keyboard and consumer control collections
in hid-multitouch.
With the previous hid-input fix, there is now a full support of the Type
Cover and we can remove all specific bits from hid-core and hid-microsoft.

hid-multitouch will automatically set HID_QUIRK_NO_INIT_REPORTS so we can
also remove it from the list of ushbid quirks.
