There is a bug in keypad_probe() where we do: kp->irq_press = platform_get_irq_byname(pdev, "press"); kp->irq_release = platform_get_irq_byname(pdev, "release"); if (kp->irq_press < 0 || kp->irq_release < 0) { The problem is that these irq variables are unsigned so the error handling doesn't work. I've changed them to signed values. Signed-off-by:Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by:

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. Signed-off-by:

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. [ 3.439537] i8042: No controller found Signed-off-by:

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. Signed-off-by:

evdev always tries to allocate the event buffer for clients using kzalloc rather than vmalloc, presumably to avoid mapping overhead where possible. However, drivers like bcm5974, which claims support for reporting 16 fingers simultaneously, can have an extraordinarily large buffer. The resultant contiguous order-4 allocation attempt fails due to fragmentation, and the device is thus unusable until reboot. Try kzalloc if we can to avoid the mapping overhead, but if that fails, fall back to vzalloc. Signed-off-by:

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. BugLink: http://bugs.launchpad.net/bugs/1229361Signed-off-by:

This patch adds a PWM dependency to configure the INPUT_MAX8997_HAPTIC and INPUT_PWM_BEEPER. Without this patch, build system can lead to build failure. This was observed during randconfig testing, in which INPUT_MAX8997_HAPTIC or INPUT_PWM_BEEPER was enabled w/o PWM being enabled, leading to the following errors: init/built-in.o drivers/built-in.o: In function `max8997_haptic_disable': :(.text+0x1073a0): undefined reference to `pwm_disable' drivers/built-in.o: In function `max8997_haptic_remove': :(.text+0x1073fc): undefined reference to `pwm_free' drivers/built-in.o: In function `max8997_haptic_play_effect_work': :(.text+0x1074f0): undefined reference to `pwm_config' :(.text+0x1075b0): undefined reference to `pwm_enable' drivers/built-in.o: In function `max8997_haptic_probe': :(.text+0x1076f8): undefined reference to `pwm_request' :(.text+0x1077e8): undefined reference to `pwm_free' drivers/built-in.o: In function `pwm_beeper_resume': :(.text+0x1081a4): undefined reference to `pwm_config' make: *** [vmlinux] Error 1 Signed-off-by:

It wasn't really clear from the gamepad-API description how ABS values are mapped exactly. Clarify that negative is left/up and positive is right/down. Unfortunately, this means I screwed up the Wii U ProController ABI. Anyhow, this just means we continue to have 0 compatible gamepad drivers in the kernel. User-space needs to fix them up, anyway, as all other gamepads are also incompatible. Signed-off-by:
