Pull input fixes from Dmitry Torokhov: "Fixes to various USB drivers to validate existence of endpoints before trying to use them, fixes to APLS v8 protocol, and a couple of i8042 quirks" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: ALPS - fix trackstick button handling on V8 devices Input: ALPS - fix V8+ protocol handling (73 03 28) Input: sur40 - validate number of endpoints before using them Input: kbtab - validate number of endpoints before using them Input: hanwang - validate number of endpoints before using them Input: yealink - validate number of endpoints before using them Input: ims-pcu - validate number of endpoints before using them Input: cm109 - validate number of endpoints before using them Input: iforce - validate number of endpoints before using them Input: elan_i2c - add ASUS EeeBook X205TA special touchpad fw Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux list Input: synaptics-rmi4 - prevent null pointer dereference in f30 Input: i8042 - add noloop quirk for Dell Embedded Box PC 3000

Input: synaptics-rmi4 - prevent null pointer dereference in f30

2017-03-10T18:22:53+00:00

If the platform data has f30_data.disable set, f30 in rmi_f30_config() might be null. Prevent a kernel oops by checking for non-null f30. Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button count

2017-03-01T18:01:56+00:00

INPUT_PROP_BUTTONPAD is currently only set through the platform data. The RMI4 header doc says that this property is there to force the buttonpad property, so we also need to detect it by looking at the exported buttons count.

Input: synaptics-rmi4 - forward upper mechanical buttons to PS/2 guest

2017-02-09T21:01:34+00:00

On the latest series of ThinkPads, the button events for the TrackPoint are reported through the touchpad itself as opposed to the TrackPoint device. In order to report these buttons properly, we need to forward them to the TrackPoint device and notify psmouse to send the button presses/releases.

Input: synaptics-rmi4 - clean up F30 implementation

2017-02-09T21:01:33+00:00

This patch does several cleanup changes to F30 code - switch to using BIT() macro - use DIV_ROUND_UP() where appropriate - factor out code setting up and reporting buttons - use single loop when reporting buttons: arithmetic is cheap compared to conditionals and associated branch misprediction.

Input: synaptics-rmi4 - select 'SERIO' when needed

2017-02-07T22:31:45+00:00

With CONFIG_SERIO=m, we get a build error for the rmi4-f03 driver, added in linux-4.10: warning: (HID_RMI) selects RMI4_F03 which has unmet direct dependencies (!UML && INPUT && RMI4_CORE && (SERIO=y || RMI4_CORE=SERIO)) drivers/input/built-in.o: In function `rmi_f03_attention': rmi_f03.c:(.text+0xcfe0): undefined reference to `serio_interrupt' rmi_f03.c:(.text+0xd055): undefined reference to `serio_interrupt' drivers/input/built-in.o: In function `rmi_f03_remove': rmi_f03.c:(.text+0xd115): undefined reference to `serio_unregister_port' drivers/input/built-in.o: In function `rmi_f03_probe': rmi_f03.c:(.text+0xd209): undefined reference to `__serio_register_port' An earlier patch tried to fix this, but missed the HID_RMI driver that does a 'select' on the F03 backend. This adds a hidden Kconfig symbol that enforces 'serio' to be enabled when RMI4-F03 is, which covers all cases.

Input: synaptics-rmi4 - fix error return code in rmi_probe_interrupts()

Fix to return error code -ENOMEM from the devm_kzalloc() error handling case instead of 0, as done elsewhere in this function. Fixes: 6bd0dcfacf28 ("Input: synaptics-rmi4 - factor out functions from probe") Signed-off-by: Wei Yongjun Reviewed-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

If a function needs to communicate with an other, it's better to have a way to retrieve this other. Reviewed-by: Andrew Duggan Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov
