Input device must be allocated (but not necessarily registered) before requesting IRQs, otherwise there is a chance that IRQ handler fires and tries to reference not yet allocated input device. Also it makes sense to store relative IRQ numbers in max8925_onkey_info structure as they are needed in suspend/resume which we expect to be called more often than probe and remove. Acked-by:

This fixes reference-before-check problem; there is no reason to check if caller passed NULL dev or bus_ops as it is done only by bus-specific drivers which already do the right thing. Reported-by:

The Data Modul TP 72037 EasyTouch controller is derived from EGALAX controller and is capable of detecting dual contacts. Packets can be 5 bytes or 10 bytes long, depending whether one or two contacts are detected. Format is same as EGALAX touch controller, but with x and y coordinates inverted. Signed-off-by:

This patch adds a driver for Synaptics USB touchpad or pointing stick devices. These USB devices emulate an USB mouse by default, so one can also use the usbhid driver. However, in combination with special user space drivers this kernel driver allows one to customize the behaviour of the device. An extended version of this driver with support for the cPad background display can be found at <http://jan-steinhoff.de/linux/synaptics-usb.html>. Signed-off-by:

As noted by Arve and others, since wall time can jump backwards, it is difficult to use for input because one cannot determine if one event occurred before another or for how long a key was pressed. However, the timestamp field is part of the kernel ABI, and cannot be changed without possibly breaking existing users. This patch adds a new IOCTL that allows a clockid to be set in the evdev_client struct that will specify which time base to use for event timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME). For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but in the future we could support other clockids if appropriate. The default remains CLOCK_REALTIME, so we don't change the ABI.

Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This driver add support for a variety of TTSP controllers. Since the hardware is capable of tracking identifiable contacts, multi-touch protocol type B (stateful) is used to report contact information. The driver is composed of a core driver that process the data sent by the contacts and a set of bus specific interface modules. This patch adds the base core TTSP driver. Signed-off-by:

We don't actually care if the device has been runtime suspended immediately so we can just drop the reference without waiting for any state change to be implemented. This may allow us to avoid some suspend/resume cycles and is a bit more friendly to the rest of the system. 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:
