ips: use interruptible waits in ips-monitor

2011-06-03T01:34:16+00:00

commit a3424216e4935221fdaa5ca3c26e024f11297164 upstream.

This is what I intended to do since:
  1) the driver handles variable waits just fine, and
  2) interruptible waits aren't reported as load in the load avg.

thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.

2011-05-21T22:13:04+00:00

commit 9fbdaeb4f4dd14a0caa9fc35c496d5440c251a3a upstream.

The newer Lenovo ThinkPads have HKEY HID of LEN0068 instead
of IBM0068. Added new HID so that thinkpad_acpi module will
auto load on these newer Lenovo ThinkPads.

ideapad: read brightness setting on brightness key notify

2011-05-02T16:19:41+00:00

commit 2165136585b5c7d6f118f1d90fbde550bb7de212 upstream.

BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=25922

On ideapad Y530, the brightness key notify will be blocked if the last notify
is not responsed by getting the brightness value. Read value when we get the
notify shall fix the problem and will not have any difference on other ideapads.

acer-wmi: does not set persistence state by rfkill_init_sw_state

2011-04-14T20:02:38+00:00

commit 8215af019040ce9182728afee9642d8fdeb17f59 upstream.

Acer BIOS keeps devices state when system reboot, but reset to default
device states (Wlan on, Bluetooth off, wwan on) if system cold boot.
That means BIOS's initial state is not always real persistence.

So, removed rfkill_init_sw_state because it sets initial state to
persistence then replicate to other new killswitch when rfkill-input
enabled.
After removed it, acer-wmi set initial soft-block state after rfkill
register, and doesn't allow set_block until rfkill initial finished.

dell-laptop: Toggle the unsupported hardware killswitch

2011-02-21T22:06:21+00:00

It is found on Dell Inspiron 1018 that the firmware reports that the hardware
killswitch is not supported. This makes the rfkill key not functional.

This patch forces the driver to toggle the firmware rfkill status in the case
that the hardware killswitch is indicated as unsupported by the firmware.

thinkpad_acpi: Always report scancodes for hotkeys

2011-02-21T22:06:20+00:00

Some thinkpad hotkeys report key codes like KEY_FN_F8 when something
like KEY_VOLUMEDOWN is desired. Always provide the scan codes in
addition to the key codes to assist with debugging these issues. Also
send the scan code before the key code to match what other drivers do,
as some userspace utilities expect this ordering.

platform/x86: ideapad-laptop depends on INPUT

2011-02-21T22:06:17+00:00

Most platform/x86 drivers that use INPUT_SPARSEKMAP also depend on INPUT,
so do the same for ideapad-laptop.  This fixes a kconfig warning and
subsequent build errors when CONFIG_INPUT is disabled.

says that at least one of these setting is experimental.
