hp-wmi: limit hotkey enable

2015-10-03T11:49:18+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

2015-09-29T17:26:15+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.

dell-laptop: Fix allocating & freeing SMI buffer page

2015-08-03T16:29:16+00:00

commit b8830a4e71b15d0364ac8e6c55301eea73f211da upstream.

This commit fix kernel crash when probing for rfkill devices in dell-laptop
driver failed. Function free_page() was incorrectly used on struct page *
instead of virtual address of SMI buffer.

This commit also simplify allocating page for SMI buffer by using
__get_free_page() function instead of sequential call of functions
alloc_page() and page_address().

ideapad: fix software rfkill setting

2015-08-03T16:29:16+00:00

commit 4b200b4604bec3388426159f1656109d19fadf6e upstream.

This fixes a several year old regression that I found while trying
to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant
to send a command to the embedded controller through ACPI, but
as of c1f73658ed, it sends the index of the rfkill device instead
of the command, and ignores the opcode field.

This changes it back to the original behavior, which indeed
flips the rfkill state as seen in the debugfs interface.

thinkpad_acpi: Revert unintentional device attribute renaming

2015-05-20T09:18:12+00:00

The conversion to DEVICE_ATTR_* macros failed to fixup a few cases where
the old attribute names didn't match the show/store function names.
Instead of renaming the functions, the attributes were renamed. This
caused an unintentional API change.  The hwmon required 'name' attribute
were among the renamed attribute, causing libsensors to fail to detect
the hwmon device at all.

Fix by using the DEVICE_ATTR macro for these attributes, allowing the
show/store functions to keep their system specific prefixes.

ideapad_laptop: Add Lenovo G40-30 to devices without radio switch

2015-05-03T18:03:36+00:00

Lenovo G40-30 does not provide any physical radio switch to user.
Therefore disable the rfkill switch identically to the Yoga 2 approach.
(Note for later, models ids are sorted alphabetically).

Benefit is to make wireless available again without unloading module.

It was tested successfully on 4.1.0-rc1 base with this model:
(LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).

Pull chrome platform updates from Olof Johansson:
 "Here's a set of updates to the Chrome OS platform drivers for this
  merge window.

  Main new things this cycle is:

   - Driver changes to expose the lightbar to users.  With this, you can
     make your own blinkenlights on Chromebook Pixels.

   - Changes in the way that the atmel_mxt trackpads are probed.  The
     laptop driver is trying to be smart and not instantiate the devices
     that don't answer to probe.  For the trackpad that can come up in
     two modes (bootloader or regular), this gets complicated since the
     driver already knows how to handle the two modes including the
     actual addresses used.  So now the laptop driver needs to know more
     too, instantiating the regular address even if the bootloader one
     is the probe that passed.

   - mfd driver improvements by Javier Martines Canillas, and a few
     bugfixes from him, kbuild and myself"
