The commit 5d9f40b56630 ("platform/x86: ideapad-laptop: Add Y520-15IKBN to no_hw_rfkill") added the entry for Y20-15IKBN, and it turned out that another variant, Y20-15IKBM, also requires the no_hw_rfkill. Trim the last letter from the string so that it matches to both Y20-15IKBN and Y20-15IKBM models.

Lenovo Yoga (many variants: Yoga, Yoga2 Pro, Yoga2 13, Yoga3 Pro, Yoga 3 14, etc) has multiple modles that are a hybrid laptop, working in laptop mode as well as tablet mode. Currently, there is no easy interface to determine the touchpad status, which in case of the Yoga family of machines, can also be useful to assume tablet mode status. Note: The ideapad-laptop driver does not provide a SW_TABLET_MODE either.

2017-01-22platform/x86: ideapad-laptop: handle ACPI event 1Zach Ploskey
On Ideapad laptops, ACPI event 1 is currently not handled. Many models log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while running on battery power. Some convertible laptops receive this event when switching in and out of tablet mode. This adds and additional case for event 1 in ideapad_acpi_notify to call ideapad_input_report(priv, vpc_bit), so that the event is reported to userspace and we avoid unnecessary logging.

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.

2015-08-10ideapad-laptop: add alternative representation for Yoga 2 to DMI tableSebastian Krzyszkowiak
There is at least one (mine) Yoga 2 Pro in existence that has incorrect product version stored in DMI (reading as "INVALID"), causing it to not be recognized as Yoga 2 by ideapad-laptop module, which in turn causes non-existent hardware rfkills to be always reported as blocked. This change adds a second check by board name, which is "Yoga2". Looks like it also happens to be "INVALID" on some other Yoga 2 machines where product version is correct instead, so the original check is left intact to catch both cases.

2015-06-15ideapad: fix software rfkill settingArnd Bergmann
This fixes a several year old regression that I found while trying to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant to send a command to the embedded controller through ACPI, but as of c1f73658ed, it sends the index of the rfkill device instead of the command, and ignores the opcode field. This changes it back to the original behavior, which indeed flips the rfkill state as seen in the debugfs interface.

2015-05-03ideapad_laptop: Add Lenovo G40-30 to devices without radio switchPhilippe Coval
Lenovo G40-30 does not provide any physical radio switch to user. Therefore disable the rfkill switch identically to the Yoga 2 approach. (Note for later, models ids are sorted alphabetically). Benefit is to make wireless available again without unloading module. It was tested successfully on 4.1.0-rc1 base with this model: (LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).

2014-12-03platform: x86: Deletion of checks before backlight_device_unregister()Markus Elfring
The backlight_device_unregister() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
