HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large

2018-06-25T23:51:31+00:00

commit d471b6b22d37bf9928c6d0202bdaaf76583b8b61 upstream.

The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains
a typo which defines an incorrect logical maximum Y value. This causes
a small portion of the bottom of the tablet to become unusable (both
because the area is below the "bottom" of the tablet and because
'wacom_wac_event' ignores out-of-range values). It also results in a
skewed aspect ratio.

To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites
the data with the correct value.

HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation

2018-06-25T23:51:31+00:00

commit ebeaa367548e9e92dd9374b9464ff6e7d157117b upstream.

Current ISH driver only registers suspend/resume PM callbacks which don't
support hibernation (suspend to disk). Basically after hiberation, the ISH
can't resume properly and user may not see sensor events (for example: screen
		rotation may not work).

User will not see a crash or panic or anything except the following message
in log:

	hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device

So this patch adds support for S4/hiberbation to ISH by using the
SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
and resume functions will now be used for both suspend to RAM and hibernation.

If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
and resume related functions won't be used, so mark them as __maybe_unused to
clarify that this is the intended behavior, and remove #ifdefs for power
management.

HID: i2c-hid: Add RESEND_REPORT_DESCR quirk for Toshiba Click Mini L9W-B

2018-05-09T11:58:01+00:00

The 0457:10fb touchscreen found on the Toshiba Click Mini L9W-B needs
to have a report-decriptors command send to it on resume in order for
the touchscreen to start generating events again on resume.

HID: intel-ish-hid: use put_device() instead of kfree()

2018-04-26T12:36:43+00:00

Never directly free @dev after calling device_register(), even
if it returned an error. Always use put_device() to give up the
reference initialized.

HID: intel_ish-hid: Stop using a static local buffer in get_report()

2018-04-25T08:52:42+00:00

hid_ishtp_get_report() may be called by multiple callers at the same
time, causing trouble with the static local buffer used.

Also there is no reason to use a non stack buffer, the buffer is tiny
and ishtp_cl_send() copies its contents so the lifetime is not an
issue either.

HID: intel_ish-hid: Move header size check to inside the loop

2018-04-25T08:52:42+00:00

With the headersize check outside of the loop, the second time through
the loop the: "payload_len = recv_msg->hdr.size;" statement may deref
recv_msg while it is pointing outside of our input buffer.

Move the headersize check to inside the loop to fix this.

HID: lenovo: Add support for IBM/Lenovo Scrollpoint mice

2018-04-25T08:48:35+00:00

The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a
scrolling wheel capable of 2-D (vertical+horizontal) scrolling.  hid-generic
does only expose 1-D (vertical) scrolling functionality for these mice.  This
patch adds support for horizontal scrolling for the IBM/Lenovo Scrollpoint mice
to hid-lenovo.

HID: i2c-hid: fix inverted return value from i2c_hid_command()

2018-04-19T07:25:15+00:00

i2c_hid_command() returns non-zero in error cases (the actual
errno). Error handling in for I2C_HID_QUIRK_RESEND_REPORT_DESCR
case in i2c_hid_resume() had the check inverted; fix that.

HID: i2c-hid: Fix resume issue on Raydium touchscreen device

2018-04-12T13:06:18+00:00

When Rayd touchscreen resumed from S3, it issues too many errors like:
i2c_hid i2c-RAYD0001:00: i2c_hid_get_input: incomplete report (58/5442)

And all the report data are corrupted, touchscreen is unresponsive.

Fix this by re-sending report description command after resume.
Add device ID as a quirk.
