Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: "First round of updates for the input subsystem. You will get a new touchsreen driver for Cypress 4th generation devices, a driver for a special controller implementing PS/2 protocol in OLPC devices, and a driver for power key for SiRFprimaII PWRC. HID and bcm5497 now support for the 2013 MacBook Air. EVIOCGKEY and the rest of evdev ioctls now flush events of matching type from the client's event queue so that clients can be sure any events received after issuing EVIOCG* ioctl are new events. And a host of cleanups and improvements in other drivers" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (87 commits) Input: cyttsp4 - kfree xfer_buf on error path in probe() Input: tps6507x-ts - select INPUT_POLLDEV Input: bcm5974 - add support for the 2013 MacBook Air HID: apple: Add support for the 2013 Macbook Air Input: cyttsp4 - leak on error path in probe() Input: cyttsp4 - silence NULL dereference warning Input: cyttsp4 - silence shift wrap warning Input: tps6507x-ts - convert to polled input device infrastructure ARM: davinci: da850-evm: remove vref from touchscreen platform data Input: cyttsp4 - SPI driver for Cypress TMA4XX touchscreen devices Input: cyttsp4 - I2C driver for Cypress TMA4XX touchscreen devices Input: cyttsp4 - add core driver for Cypress TMA4XX touchscreen devices Input: cyttsp - I2C driver split into two modules Input: add OLPC AP-SP driver Input: nspire-keypad - remove redundant dev_err call in nspire_keypad_probe() Input: tps6507x-ts - remove vref from platform data Input: tps6507x-ts - use bool for booleans Input: tps6507x-ts - remove bogus unreachable code Input: samsung-keypad - let device core setup the default pin configuration Input: wacom_i2c - implement hovering capability ...
