Input: wacom - make sure touch_max is set for touch devices

2014-03-31T16:58:14Z

commit 1d0d6df02750b4a6f466768cbfbf860e24f4c8d4 upstream. Old single touch Tablet PCs do not have touch_max set at wacom_features. Since touch device at lease supports one finger, assign touch_max to 1 when touch usage is defined in its HID Descriptor and touch_max is not pre-defined.

Input: elantech - improve clickpad detection

2014-03-31T16:58:14Z

commit c15bdfd5b9831e4cab8cfc118243956e267dd30e upstream. The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.

Input - arizona-haptics: Fix double lock of dapm_mutex

2014-03-07T05:30:12Z

commit c4204960e9d0ba99459dbf1db918f99a45e7a62a upstream. snd_soc_dapm_sync takes the dapm_mutex internally, but we currently take it externally as well. This patch fixes this. Signed-off-by: Charles Keepax Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

Input: allocate absinfo data when setting ABS capability

2014-01-09T20:24:24Z

commit 28a2a2e1aedbe2d8b2301e6e0e4e63f6e4177aca upstream. We need to make sure we allocate absinfo data when we are setting one of EV_ABS/ABS_XXX capabilities, otherwise we may bomb when we try to emit this event.

Input: usbtouchscreen - separate report and transmit buffer size handling

2013-12-20T15:45:08Z

commit 4ef38351d770cc421f4a0c7a849fd13207fc5741 upstream. This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

Input: mousedev - allow disabling even without CONFIG_EXPERT

2013-12-12T06:36:28Z

commit dfaaed08ecc01bd513248ba7999daf50ce028352 upstream. Moust (if not all) modern software, including X, uses /dev/eventX rather than the legacy /dev/mouseX devices. It therefore makes sense for general-purpose (distro) kernels to use MOUSEDV=m (or even n), so let's drop the EXPERT=y requirement.

Input: allow deselecting serio drivers even without CONFIG_EXPERT

2013-12-12T06:36:28Z

commit bcd2623073e98f69f84720308db0b142c4da0bd6 upstream. There is plenty of consumer hardware (e.g., mac books) that does not use AT keyboards or PS/2 mice. It therefore makes sense for distro kernels to build the related drivers as modules to avoid loading them on hardware that does not need them. As such, these options should no longer be protected by EXPERT. Moreover, building these drivers as modules gets rid of the following ugly error during boot: [ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.

commit 78551277e4df57864b0b0e7f85c23ede2be2edb8 upstream. This allows the module to be autoloaded in the common case. In order to work on non-PnP systems the module should be compiled in or loaded unconditionally at boot (c.f. modules-load.d(5)), as before.
