If serio_raw_write was always returning number of bytes successfully sent to serio port and never signalled error condition to the caller. Change it so that for completely failed transfers appropriate error code returned to the caller (partially successful writes still return number of bytes transferred). Reported-by:

Recent conversion to module_platform_driver() went a bit too far and converted not only drivers that used platform_driver_register() but also ones using platform_driver_probe(), breaking them in process. Reported-by:

Several protocol initialization routines can fail after they set up psmouse methods, such as reconnect and disconnect. This may lead to these stale methods used with different protocol that they were intended to be used for and may cause unpredictavle behavior and/or crashes. Make sure we start with a clean slate before executing each and every protocol detection and/or initialization routine. Reported-by:

If there is a full packet in the buffer, and we overflow that buffer right after checking for that condition, it would have been possible for us to block indefinitely (rather, until the next full packet) even if the file was marked as O_NONBLOCK.

Without this, it was possible for the reader to get ahead of packet_head. If the input device generated a partial packet *right* after the reader got ahead, then we can get into a situation where the device is marked readable, but read always returns 0 until the next packet is finished (i.e a SYN is generated by the input driver). This situation can also happen if we overflow the buffer while a reader is trying to read an event out. Signed-off-by:

When runtime power management is enabled put the Samsung keypad driver into suspend mode with wakeups disabled whenever the device is open but a key is not actually been pressed. As well as saving a trivial amount of power this will support the use of SoC wide idle modes which put the entire device into a retention mode and use explicit wakeup sources to exit. Since not all of the interrupt controllers used with the driver support set_irq_wake() (though they all do the right thing) and there's a nasty WARN() when we disable wake after failing to enable it keep track of the current wake status from runtime PM and only disable wake if we managed to enable it; I'm not entirely sure why this doesn't affect the existing uses of the API in the driver. System suspend is unaffected as the driver core will runtime resume any suspended devices prior to system suspend. Signed-off-by:

Some displays from AUO have a so called in-cell touchscreen, meaning it is built directly into the display unit. Touchdata is gathered through PIXCIR Tango-ICs and processed in an Atmel ATmega168P with custom firmware. Communication between the host system and ATmega is done via I2C. Devices using this touch solution include the Dell Streak5 and the family of Qisda ebook readers. The driver reports single- and multi-touch events including touch area values. Signed-off-by:

The Cintiq 24HD has three LEDs on the left side of the tablet and three LEDs on the right side of the tablet. Switching to LED 0, 1, or 2 will enable the top, middle, or bottom LED for the respective side. Switching to LED 3 turns off the LEDs on the respective side. Signed-off-by:

Adds support for the Cintiq 24HD. There are two quirks about this model that haven't been seen in prior tablets. First, a second touch ring is present on this display; it is being exposed via the ABS_THROTTLE axis. Second, three capacitive buttons at the top of the unit are available; though physically a touch strip, we report the use of these buttons with generic KEY_ events. Signed-off-by:

Synaptics touchpads on several Dell laptops, particularly Vostro V13 systems, may not respond properly to PS/2 commands and queries immediately after resuming from suspend to RAM. This leads to unresponsive touchpad after suspend/resume cycle. Adding a 1-second delay after resetting the device allows touchpad to finish initializing (calibrating?) and start reacting properly.

This driver adds support for Sharp's GP2AP002A00F proximity sensor. The proximity is measured as a binary switch, i.e. an object is either detected or not detected. Hence, this driver is implemented as a switch that reports SW_FRONT_PROXIMITY. Reviewed-by:
