platform/x86: acer-wmi: setup accelerometer when ACPI device was found

2017-05-09T06:19:25Z

commit f9ac89f5ad613b462339e845aeb8494646fd9be2 upstream. The 98d610c3739a patch was introduced since v4.11-rc1 that it causes that the accelerometer input device will not be created on workable machines because the HID string comparing logic is wrong. And, the patch doesn't prevent that the accelerometer input device be created on the machines that have no BST0001. That's because the acpi_get_devices() returns success even it didn't find any match device. This patch fixed the HID string comparing logic of BST0001 device. And, it also makes sure that the acpi_get_devices() returns acpi_handle for BST0001.

platform/x86: acer-wmi: setup accelerometer when machine has appropriate notify event

2017-05-03T12:46:51Z

commit 98d610c3739ac354319a6590b915f4624d9151e6 upstream. The accelerometer event relies on the ACERWMID_EVENT_GUID notify. So, this patch changes the codes to setup accelerometer input device when detected ACERWMID_EVENT_GUID. It avoids that the accel input device created on every Acer machines. In addition, patch adds a clearly parsing logic of accelerometer hid to acer_wmi_get_handle_cb callback function. It is positive matching the "SENR" name with "BST0001" device to avoid non-supported hardware.

acer-wmi: Add acpi_backlight=video quirk for the Acer KAV80

2014-11-13T18:03:06Z

commit 183fd8fcd7f8afb7ac5ec68f83194872f9fecc84 upstream. The acpi-video backlight interface on the Acer KAV80 is broken, and worse it causes the entire machine to slow down significantly after a suspend/resume. Blacklist it, and use the acer-wmi backlight interface instead. Note that the KAV80 is somewhat unique in that it is the only Acer model where we fall back to acer-wmi after blacklisting, rather then using the native (e.g. intel) backlight driver. This is done because there is no native backlight interface on this model.

acer-wmi: support Lenovo ideapad S205 1038DPG wifi switch

2013-02-24T22:49:56Z

Found another Lenovo ideapad S205 the product name is 1038DPG, it has a 0x78 EC register exposes the state of wifi hardware switch on the machine. So, add this patch to support Lenovo ideapad S205-1038DPG wifi hardware switch in acer-wmi driver. Evidently the Ideapad S205 is just a model name on the market, but they have totally different product name in DMI table.

KEY_TOUCHPAD_TOOGLE key is for notice userland change touchpad state via xf86-input-synaptics on the machine that don't toggle touchpad in hardware. But, acer laptop actually toggle touchpad in hardware. So, this patch change to emit KEY_TOUCHPAD_ON/OFF key when acer-wmi grab device state of touchpad.

Drivers: platform: x86: remove __dev* attributes.

2013-01-03T23:57:03Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
