Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid

Pull HID updates from Jiri Kosina:

 - open/close tracking improvements from Dmitry Torokhov

 - battery support improvements in Wacom driver from Jason Gerecke

 - Win8 support fixes from Benjamin Tissories and Hans de Geode

 - misc fixes to Intel-ISH driver from Arnd Bergmann

 - support for quite a few new devices and small assorted fixes here and
   there

+ * struct i2chid_platform_data - used by hid over i2c implementation.
+ * @hid_descriptor_address: i2c register where the HID descriptor is stored.
+ * @supply: regulator for powering on the device.
+ * @post_power_delay_ms: delay after powering on before device is usable.
+ *
+ * Note that it is the responsibility of the platform driver (or the acpi 5.0
+ * driver, or the flattened device tree) to setup the irq related to the gpio in
+ * the struct i2c_board_info.
+ * The platform driver should also setup the gpio according to the device:
+ *
+ * A typical example is the following:
+ *	irq = gpio_to_irq(intr_gpio);
+ *	hkdk4412_i2c_devs5[0].irq = irq; // store the irq in i2c_board_info
+ *	gpio_request(intr_gpio, "elan-irq");
+ *	s3c_gpio_setpull(intr_gpio, S3C_GPIO_PULL_UP);
