acer-wmi: No wifi rfkill on Sony machines

2012-04-13T15:14:08+00:00

commit 5719b81988f3c24ff694dc3a37e35b35630a3966 upstream.

The wireless rfkill should charged by sony-laptop but not acer-wmi.
So, add Sony's SNY5001 acpi device to blacklist in acer-wmi.

Tested on Sony Vaio

acer-wmi: No wifi rfkill on Lenovo machines

2012-03-19T15:57:45+00:00

commit 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a upstream.

We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.

Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.

acer-wmi: check wireless capability flag before register rfkill

2012-03-19T15:57:45+00:00

commit 1709adab0773616da7a8190f2762e599afb0a295 upstream.

There will be better to check the wireless capability flag
(ACER_CAP_WIRELESS) before register wireless rfkill because maybe
the machine doesn't have wifi module or the module removed by user.

Tested on Acer Travelmate 8572

acer-wmi: Add wireless quirk for Lenovo 3000 N200

2012-03-19T15:57:44+00:00

commit be3128b107e36271f7973ef213ccde603a494fe8 upstream.

This quirk fixes the wlan rfkill status on this machine. Without
it, wlan is permanently soft blocked whenever acer-wmi is loaded.

acer-wmi: support Lenovo ideapad S205 wifi switch

2012-03-19T15:57:44+00:00

commit 15b956a0b5651bbb1217ec374fdd67291dabb2af upstream.

The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control
the wifi hardware state. We also found there have a 0x78 EC register
exposes the state of wifi hardware switch on the machine.

So, add this patch to support Lenovo ideapad S205 wifi hardware switch
in acer-wmi driver.

commit 023b9565972a4a5e0f01b9aa32680af6e9b5c388 upstream.

We need to remove devices that we destroy from the list, otherwise
we'll crash if there are more than one "_WDG" methods in DSDT.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=32052

platform: samsung_laptop: fix samsung brightness min/max calculations

2011-11-11T17:35:48+00:00

commit bee460be8c691c544e84ed678280ace6153104c6 upstream.

The min_brightness value of the sabi_config is incorrectly used in brightness
calculations. For the config where min_brightness = 1 and max_brightness = 8,
the user visible range should be 0 to 7 with hardware being set in the range
of 1 to 8. What is actually happening is that the user visible range is 0 to
8 with hardware being set in the range of -1 to 7.

This patch fixes the above issue as well as a miscalculation that would occur
in the case of min_brightness > 1.
