platform/x86: asus-wmi: Remove quirk_no_rfkill

2017-03-12T23:41:55Z

With the detection introduced in the previous patches, we don't need these static DMI-based quirks anymore. This reverts the following commits: 56a37a72002b "asus-wmi: Add quirk_no_rfkill_wapf4 for the Asus X456UA" a961a285b479 "asus-wmi: Add quirk_no_rfkill_wapf4 for the Asus X456UF" 6b7ff2af5286 "asus-wmi: Add quirk_no_rfkill for the Asus Z550MA" 02db9ff7af18 "asus-wmi: Add quirk_no_rfkill for the Asus U303LB" 2d735244b798 "asus-wmi: Add quirk_no_rfkill for the Asus N552VW" a977e59c0c67 "asus-wmi: Create quirk for airplane_mode LED" Signed-off-by: João Paulo Rechi Vita Signed-off-by: Andy Shevchenko [dvhart: minor commit message corrections] Signed-off-by: Darren Hart (VMware)

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:27Z

We are going to split out of , which will have to be picked up from a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDT

2017-02-26T15:01:48Z

Some Asus laptops that have an airplane-mode indicator LED, also have the WMI WLAN user bit set, and the following bits in their DSDT: Scope (_SB) { (...) Device (ATKD) { (...) Method (WMNB, 3, Serialized) { (...) If (LEqual (IIA0, 0x00010002)) { OWGD (IIA1) Return (One) } } } } So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the wlan state, it drives the airplane-mode indicator LED (through the call to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF (since wlan is ON), and vice-versa. This commit skips registering RFKill switches at all for these laptops, to allow the asus-wireless driver to drive the airplane mode LED correctly through the ASHS ACPI device. Relying on the presence of ASHS and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least 21 different laptops. Signed-off-by: João Paulo Rechi Vita Signed-off-by: Andy Shevchenko

platform/x86: fujitsu-laptop: remove redundant MODULE_ALIAS entries

2017-02-26T15:01:48Z

MODULE_DEVICE_TABLE is all that is needed for fujitsu-laptop to be properly autoloaded based on presence of its associated ACPI devices, so remove redundant MODULE_ALIAS entries.

platform/x86: fujitsu-laptop: autodetect LCD interface on all models

2017-02-26T15:01:48Z

Presence of ACPI method SBL2 should be checked on all models rather than just the ones with predefined hotkey keycode overrides. Move most of dmi_check_cb_common() to acpi_fujitsu_bl_add(). Adjust indentation to make checkpatch happy.

platform/x86: fujitsu-laptop: simplify acpi_bus_register_driver() error handling

2017-02-26T15:01:07Z

A separate variable is not needed to handle error codes returned by acpi_bus_register_driver(). If the latter fails, just use the value it returned as the value returned by fujitsu_init().

Both acpi_fujitsu_bl_notify() and acpi_fujitsu_laptop_notify() are defined before they are first used, so remove their forward declarations as they are redundant.

platform/x86: fujitsu-laptop: rename FUNC_RFKILL to FUNC_FLAGS

2017-02-26T15:01:07Z

FUNC subfunction 0x1000 is currently referred to as FUNC_RFKILL, which is misleading, because it handles more than just radio devices (also lid, dock, LEDs). Rename the FUNC_RFKILL constant to FUNC_FLAGS. Replace "rfkill" with "flags" in the names of its associated fields inside struct fujitsu_laptop.
