These are a couple smatch issues. In the original code, if only one of the allocation fails we leak the other variable so we should goto out_free_mem. Also there was a use after free if debugging was enabled and so I moved the kfree() down a line. Signed-off-by:

Some laptops, such as Lenovo 3000 N100, require keyboard controller reset in order to have touchpad operable after suspend to RAM. Even if box does not need the reset it should be safe to do so, so instead of chasing after misbehaving boxes and grow DMI tables, let's reset the controller unconditionally. Reported-and-tested-by:

Reporting this will allow GUI config apps to correctly scale width sensitive config values (such as palm detect) to correct range. Current user apps are detecting kernels min/max=0/0 and making an assumption that it means 0/16 or 0/15. Synaptics touchpad interface guides show 4/15 are correct values but driver forces to 0 when no fingers on touchpad. Signed-off-by:

Synaptics devices report fixed value of 5 for finger/palm widths on devices that do not support capability and driver further hardcodes to 5. Stop reporting this fixed value when its not supported since its not useful. This will aid applications so they can better auto-enable support for multi-touch emulation and palm detection logic using finger width only for devices that support width detection. I can find no applications that currently require existence on ABS_TOOL_WIDTH. Since only synaptics and bcm input devices currently support this tool, it seems they must handle it gracefully.

With the rapidly increasing number of intelligent multi-contact and multi-user devices, the need to send digested, filtered information from a set of different sources within the same device is imminent. This patch adds the concept of slots to the MT protocol. The slots enumerate a set of identified sources, such that all MT events can be passed independently and selectively per identified source. The protocol works like this: Instead of sending a SYN_MT_REPORT event immediately after the contact data, one sends an ABS_MT_SLOT event immediately before the contact data. The input core will only emit events for slots with modified MT events. It is assumed that the same slot is used for the duration of an initiated contact. Acked-by:

Dance pads don't have any axes/sticks, only buttons for directions. For example buttons like left+right will get triggered at once, an axis can't handle this anyway. So this patch adds a module parameter named "sticks_to_null" for unknown devices. A known dance pad makes use of it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other tested devices may follow by adding this mapping-option too. Some buttons of xpad-devices are addressing mouse-buttons instead of gamepad-buttons. This gets fixed too. Signed-off-by:

ADS7845 is a controller for 5-wire touch screens and somewhat different from 7846. It requires three serial communications to accomplish one complete conversion. Unlike 7846 it doesn't allow Z1-/Z2- position measurement. The patch extends the ads7846 driver to also support ads7845. The packet struct is extended to contain needed command and conversion buffers. ads7846_rx() and ads7846_rx_val() now differentiate between 7845 and 7846 case. ads7846_probe() is modified to setup ads7845 specific command and conversion messages and to switch ads7845 into power-down mode, since this is needed to be prepared to respond to pendown interrupts.

gpiolib now has debounce support added in .35, so let's make use of it. This allows to use hardware GPIO debouncing on some platforms like OMAP. In case gpiolib debounce setup fails for some GPIO, the driver will fall back to timer based debouncing, which is what it used before. Signed-off-by:
