2014-03-26Input: cypress_ps2 - don't report as a button padsHans de Goede
The cypress PS/2 trackpad models supported by the cypress_ps2 driver emulate BTN_RIGHT events in firmware based on the finger position, as part of this no motion events are sent when the finger is in the button area. The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that BTN_RIGHT events should be emulated in userspace, which is not necessary in this case. When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion event before propagating the button event higher up the stack, as it needs current abs x + y data for its BTN_RIGHT emulation. Since in the cypress_ps2 pads don't report motion events in the button area, this means that clicks in the button area end up being ignored, so INPUT_PROP_BUTTONPAD actually causes problems for these touchpads, and removing it fixes: https://bugs.freedesktop.org/show_bug.cgi?id=76341 Reported-by: Adam Williamson <awilliam@redhat.com> Tested-by: Adam Williamson <awilliam@redhat.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-01-06Input: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-10-31Input: cypress_ps2 - do not consider data bad if palm is detectedJoseph Salisbury
If hardware (or firmware) detects palm on the surface of the device it does not mean that the data packet is bad from the protocol standpoint. Instead of reporting PSMOUSE_BAD_DATA in this case simply threat it as if nothing touches the surface.

Casting the return value which is a void pointer is redundant. The conversion from void pointer to any other pointer type is guaranteed by the C programming language. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
