The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

When support for instantiating an i2c-client for the fuel-gauge was added for the Windows based Yoga Book YB1-X91F/L models, the assumption was made that this would apply to the Android based YB1-X90F/L models too. But these have a completely different BIOS with completely different DMI strings. Update the existing YB1-X91 support to reflect that it only applies to the YB1-X91F/L models.

The Yoga Tablet 2 1050/830 series have a HALL sensor for detecting when their (optional) case/cover is closed over the screen. Their Windows counterparts (alsmost the same HW, different BIOS) model this as a LID switch. Add support for reporting this as a LID switch on the Android models too. Signed-off-by:

The YT3 uses an TI LP8557 LED backlight controller, the LP8557's PWM input is connected to a PWM output coming from the LCD panel's controller. The Android kernel has a hack in the i915 driver to write the non-standard DSI reg 0x51 with the desired level to set the duty-cycle of the LCD's PWM. To avoid having to have a similar hack in the mainline kernel program instantiate an i2c-client for the LP8557 with platform-data to have the LP8557 to directly set the level (ignoring its PWM input), this allows backlight brightness control through a backlight device registered by the lp855x_bl driver.

The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this. Signed-off-by:

The Acer Iconia One 7 B1-750 is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. Signed-off-by:

User space can get the API version using IOCTL ISST_IF_GET_PLATFORM_INFO. This information can be used to get IOCTLs supported by the kernel driver. This version is hardcoded in the driver. Allow the registered client to specify the supported API version. In this way a registered client can specify a higher API version to extend IOCTL set. Signed-off-by:

The common IOCTL handler has a predefined list of IOCTLs it can handle. There is no default handler, if there is no match. Allow a client driver to define their own version of default IOCTL callback. In this way the default handling is passed to the client drivers to handle. With the introduction of TPMI target, IOCTL list is extended. The additional TPMI specific IOCTLs will be passed to the TPMI client driver default IOCTL handler. Signed-off-by:
