toshiba_acpi: Fix hotkeys registration on some toshiba models

2015-10-22T21:49:14+00:00

commit 53147b6cabee5e8d1997b5682fcc0c3b72ddf9c2 upstream.

Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
for keymap choosing") changed the *setup_keyboard function to query for
the Hotkey Event Type to help choose the correct keymap, but turns out
that here are certain Toshiba models out there not implementing this
feature, and thus, failing to continue the input device registration and
leaving such laptops without hotkey support.

This patch changes such check, and instead of returning an error if
the Hotkey Event Type is not present, we simply inform userspace about it,
changing the message printed from err to notice, making the function
responsible for registering the input device to continue.

This issue was found on a Toshiba Portege Z30-B, but there might be
some other models out there affected by this regression as well.

hp-wmi: limit hotkey enable

2015-10-03T11:51:39+00:00

commit 8a1513b49321e503fd6c8b6793e3b1f9a8a3285b upstream.

Do not write initialize magic on systems that do not have
feature query 0xb. Fixes Bug #82451.

Redefine FEATURE_QUERY to align with 0xb and FEATURE2 with 0xd
for code clearity.

Add a new test function, hp_wmi_bios_2008_later() & simplify
hp_wmi_bios_2009_later(), which fixes a bug in cases where
an improper value is returned. Probably also fixes Bug #69131.

Add missing __init tag.

ideapad-laptop: Add Lenovo Yoga 3 14 to no_hw_rfkill dmi list

2015-09-29T17:33:34+00:00

commit fa92a31b3335478c545cdc8e79e1e9b788184e6b upstream.

Like some of the other Yoga models the Lenovo Yoga 3 14 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 3 14 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

platform/chrome: Don't make CHROME_PLATFORMS depends on X86 || ARM

2015-07-24T08:05:43+00:00

The Chrome platform support depends on X86 || ARM because there are
only Chromebooks using those architectures. But only some drivers
depend on a given architecture, and the ones that do already have
a dependency on their specific Kconfig symbol entries.

An option is to also make CHROME_PLATFORMS depends on || COMPILE_TEST
but is more future proof to remove the dependency and let the drivers
be built in all architectures if possible to have more build coverage.

dell-laptop: Do not cache hwswitch state

2015-07-06T22:35:23+00:00

The hwswitch state can be changed at runtime, so make sure dell-laptop
always knows the current state. It can be modified by the userspace
utility smbios-wireless-ctl.

dell-laptop: Clear buffer before each SMBIOS call

2015-07-06T22:33:38+00:00

Make sure that before initializing SMBIOS call, the input buffer does
not contain any garbage (e.g. values from previous SMBIOS call). This
fixes problems with passing undefined/random parameters to SMBIOS
functions.
