platform/chrome: cros_ec_sensorhub: Fix EC timestamp overflow

2020-09-03T09:29:16+00:00

[ Upstream commit e48bc01ed5adec203676c735365373b31c3c7600 ]

EC is using 32 bit timestamps (us), and before converting it to 64bit
they were not casted, so it would overflow every 4s.
Regular overflow every ~70 minutes was not taken into account either.

platform/chrome: cros_ec_ishtp: Fix a double-unlock issue

2020-08-21T11:15:04+00:00

[ Upstream commit aaa3cbbac326c95308e315f1ab964a3369c4d07d ]

In function cros_ec_ishtp_probe(), "up_write" is already called
before function "cros_ec_dev_init". But "up_write" will be called
again after the calling of the function "cros_ec_dev_init" failed.
Thus add a call of the function “down_write” in this if branch
for the completion of the exception handling.

platform/x86: asus-nb-wmi: add support for ASUS ROG Zephyrus G14 and G15

2020-08-19T06:26:20+00:00

[ Upstream commit 13bceda68fb9ef388ad40d355ab8d03ee64d14c2 ]

Add device support for the new ASUS ROG Zephyrus G14 (GA401I) and
G15 (GA502I) series.

This is accomplished by two new quirk entries (one per each series),
as well as all current available G401I/G502I DMI_PRODUCT_NAMEs to match
the corresponding devices.

platform/x86: intel-vbtn: Fix return value check in check_acpi_dev()

2020-08-19T06:26:08+00:00

[ Upstream commit 64dd4a5a7d214a07e3d9f40227ec30ac8ba8796e ]

In the function check_acpi_dev(), if it fails to create
platform device, the return value is ERR_PTR() or NULL.
Thus it must use IS_ERR_OR_NULL() to check return value.

platform/x86: thinkpad_acpi: Revert "Use strndup_user() in dispatch_proc_write()"

2020-07-15T09:42:52+00:00

This reverts commit 35d13c7a05126a5a54a1ef40aff4c6984474e604.

This broke procfs interface due to neglecting the fact that
the strings are not coming NULL terminated.

Revert the change till we will have a better clean up.

Merge branch 'i2c/for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

2020-06-13T20:12:38+00:00

Pull i2c updates from Wolfram Sang:
 "I2C has quite some patches for you this time. I hope it is the move to
  per-driver-maintainers which is now showing results. We will see.

  The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
  larger refactoring of the Designware, Tegra, and PXA drivers, the
  Cadence driver supports being a slave now, and there is support to
  instanciate SPD eeproms for well-known cases (which will be
  user-visible because the i801 driver supports it), and some
  devm_platform_ioremap_resource() conversions which blow up the
  diffstat.

  Note that I applied the Nuvoton driver quite late, so some minor fixup
  patches arrived during the merge window. I chose to apply them right
  away because they were trivial"
