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.

'{ }' and memset will both reset the cbuf buffer.
Only once is enough and this can be done outside fo the mutex.

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: Check return value of each SMBIOS call

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.
