2016-09-07mfd: cros_ec: Add cros_ec_cmd_xfer_status() helperTomeu Vizoso
commit 9798ac6d32c1a32d6d92d853ff507d2d39c4300c upstream. So that callers of cros_ec_cmd_xfer() don't have to repeat boilerplate code when checking for errors from the EC side.

2016-08-20hp-wmi: Fix wifi cannot be hard-unblockedAlex Hung
commit fc8a601e1175ae351f662506030f9939cb7fdbfe upstream. Several users reported wifi cannot be unblocked as discussed in [1]. This patch removes the use of the 2009 flag by BIOS but uses the actual WMI function calls - it will be skipped if WMI reports unsupported.

commit 096cdc6f52225835ff503f987a0d68ef770bb78e upstream. We verify "u_cmd.outsize" and "u_cmd.insize" but we need to make sure that those values have not changed between the two copy_from_user() calls. Otherwise it could lead to a buffer overflow. Additionally, cros_ec_cmd_xfer() can set s_cmd->insize to a lower value. We should use the new smaller value so we don't copy too much data to the user.

commit ff8651237f39cea60dc89b2d9f25d9ede3fc82c0 upstream. Some BIOSes unconditionally send an ACPI notification to RBTN when the system is resuming from suspend. This makes dell-rbtn send an input event to userspace as if a function key was pressed. Prevent this by ignoring all the notifications received while the device is suspended.

2016-05-04toshiba_acpi: Fix regression caused by hotkey enabling valueAzael Avalos
commit a30b8f81d9d6fe24eab8a023794548b048f08e3c upstream. Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value") changed the hotkeys enabling value, as it was the same value Windows uses, however, it turns out that the value tells the EC that the driver will now take care of the hardware events like the physical RFKill switch or the pointing device toggle button. This patch reverts such commit by changing the default hotkey enabling value to 0x09, which enables hotkey events only, making the hardware buttons working again. Fixes bugs 113331 and 114941.

commit 4db9675d927a71faa66e5ab128d2390d6329750b upstream. Some Lenovo ideapad models lack a physical rfkill switch.

commit bae5336f0aaedffa115dab9cb3d8a4e4aed3a26a upstream. If transflective backlight is supported and the brightness is zero (lowest brightness level), the set_lcd_brightness function will activate the transflective backlight, making the LCD appear to be turned off.

2015-11-10asus-wmi: fix error handling in store_sys_wmi()Dan Carpenter
The asus_wmi_get_devstate_simple() returns 0-1 on success. In theory according to static checkers, it can return either -EIO or -ENODEV on failure. Currently the error handling code only handles -ENODEV and -EIO is treated as success. Let's make it handle the -EIO error as well. It's possible that it can't actually return -EIO and this patch is not needed but in that case this patch is harmless and silences a static checker warning so it's still worth it.

2015-11-09ideapad-laptop: include Yoga 3 1170 in add rfkill whitelistArnd Bergmann
This changes the entry to the whitelist of machines that do not have a physical rfkill switch. Unfortunately, the Yoga 3 generation seems to use upper-case letters for the YOGA 3 Pro-1370, while it uses normal capitalization for its Yoga 3 1170 and 1470 siblings. In order to catch all variants of the Yoga 3, I'm changing both the entry for the 1470 (using "Yoga" as the name) and the entry for the Pro 1370 (using all-caps "YOGA") to not match the exact model number but only the generation. This way, the 1170 and 1470 models share one entry, but if the firmware changes from one format to the other, it will still work. The second entry for Yoga 2 Pro that was recently added for some reason ended up not being added in alphanumeric order, and I'm moving the Yoga 3 1470 entry down while making the change, so they are sorted more logically.

2015-11-09ideapad-laptop: add support for Yoga 3 ESC keyArnd Bergmann
The ideapad-laptop handles most special keys on various Lenovo Laptops including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have one important exception, which is the Fn-ESC combination. On other Lenovo Laptops, this is FnLock, which switches the function keys between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1, F2, F3, ...) behavior. On the new machines, FnLock is only available through BIOS setup (possibly through a yet-to-be-implemented feature in this driver) but not through Fn-ESC, but instead the ESC key itself switched between ESC and a "Paper Display" app for Windows. Unfortunately, that means that you can never have both ESC *and* the function keys working at the same time without needing to press Fn on one of them. As pointed out in the official Lenovo Forum by dozens of users, this makes the machine rather useless for any serious work [1]. I have now studied the ACPI DSDT one more time and found the event that is generated for the ESC key. Unlike all other key events on this machine, it is actually a WMI, while the other ones are read from the embedded controller. I am now installing a WMI notifier that uses the event number from the WMI subsystem as the scancode. The only event number generated here is '128', and that fits in nicely with the two existing ranges of scancodes used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS. The only sane way to handle this button (in absence of the Windows Paper Display driver) seems to be to have it emit KEY_ESC, so that is what I use as the default. Should any user ever want to overwrite the default, they can install their own keymap. To ensure that we can still build the driver without adding a CONFIG_WMI dependency, all new code is enclosed in #ifdef.

2015-10-07platform/chrome: Make depends on MFD_CROS_EC instead CROS_EC_PROTOJavier Martinez Canillas
The ChromeOS EC LPC and chardev drivers depend on CROS_EC_PROTO but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform devices that are matched with these drivers are registered by the ChromeOS EC mfd driver, they really depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the drivers to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

2015-10-06acer-wmi: remove threeg and interface sysfs interfacesLee, Chun-Yi
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and provides the threeg rfkill interface. So the sysfs interface of 3G is no longer necessary now. The 7b8aca65 patch added kernel information log to remind to user space for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch updated the interface removing time to 2014. I think the 3 years lead time is enough for user space application to use rfkill instead of sysfs interface to control 3G device. This patch removes code about threeg sysfs interface. And it also removes the unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi driver on the machine. The information is already exposed by the acer-wmi initial log.

2015-10-03platform/x86: Toshiba WMI Hotkey DriverAzael Avalos
Toshiba laptops that feature WMI events for hotkeys were left unsupported by the toshiba_acpi driver, however, commit a88bc06e5aec ("toshiba_acpi: Avoid registering input device on WMI event laptops") added hardware support for such laptops, but the hotkeys are not handled there. This driver adds support for hotkey monitoring on certain Toshiba laptops that manage the hotkeys via WMI events instead of the Toshiba Configuration Interface (TCI). The toshiba_acpi driver and this one can co-exist, as this only takes care of hotkeys, while the proper takes care of hardware related stuff. Currently the driver is under the EXPERIMENTAL flag, as the keymap and the notify function are incomplete (due to lack of hardware to test).
