| | | | | | | | | | | Touchpad input doesn't work with newer HP Pavilion dv4 laptops due to bad i8042 timeout data. Booting with i8042.notimeout and i8042.nomux successfully works around the problem.

| * Input: adp5589-keys - add support for the ADP5585 derivativesMichael Hennerich2011-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ADP5585 family keypad decoder and IO expander is similar to the ADP5589, however it features less IO pins, and lacks hardware assisted key-lock functionality. Unfortunately the register addresses are different, as well as the event codes and bit organization within the port related registers. Move ADP5589 Register defines from the header file into the main source file. Add new defines while making sure we don't break existing platform_data. Add register address translation, and turn device specific defines into variables. Introduce some helper functions and disable functions that doesn't exist on the added devices.

| * Input: imx_keypad - add pm suspend and resume supportHui Wang2011-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | The imx_keypad driver was indicating that it was wakeup capable in imx_keypad_probe(), but it didn't implement suspend or resume methods. According to the i.MX series MCU Reference Manual, the kpp (keypad port) is a major wake up source which can detect any key press even in low power mode and even when there is no clock.

| * Input: force feedback - potential integer wrap in input_ff_create()Dan Carpenter2011-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem here is that max_effects can wrap on 32 bits systems. We'd allocate a smaller amount of data than sizeof(struct ff_device). The call to kcalloc() on the next line would fail but it would write the NULL return outside of the memory we just allocated causing data corruption. The call path is that uinput_setup_device() get ->ff_effects_max from the user and sets the value in the ->private_data struct. From there it is: -> uinput_ioctl_handler() -> uinput_create_device() -> input_ff_create(dev, udev->ff_effects_max); I've also changed ff_effects_max so it's an unsigned int instead of a signed int as a cleanup.

| * Input: serio_raw - fix memory leak when closing char deviceDmitry Torokhov2011-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently we never freed memory allocated when users open our char devices nor removed old users from the list of connected clients. Also unregister misc device immediately upon disconnecting the port instead of waiting until last user drops off (refcounting in misc device code will make sure needed pieces stay around while they are needed) and make sure we are not holing holding serio_raw_mutex when registering/unregistering misc device. This should fix potential deadlock between serio_raw and misc device code uncovered by lockdep and reported by Thomas Tuttle.
