This calculation determines the physical dimensions of the tablet, used later on in calculate_touch_res to obtain the touch sensor resolution. Instead of dividing the logical size by the resolution, the current code performs a multiplication. This doesn't pose a problem for the 3rd-gen Bamboo since the resolution and scale factor happen to be identical, but will produce an incorrect result for other cases. Signed-off-by:

Commit 509f87c5 (evdev - do not block waiting for an event if fd is nonblock) created a code path were it was possible to use retval uninitialized.

ALPS touchpad detection fails if some buttons of ALPS are pressed. The reason is that the "E6" query response byte is different from what is expected. This was tested on a Toshiba Portege R500. Cc: stable <stable@vger.kernel.org> Signed-off-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:
