Input: switch to using sizeof(*type) when allocating memory

2017-05-10T21:39:34+00:00

Instead of specifying type explicitly, derive it from the type of pointer when allocating memory, which is considered safer practice. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: use seq_puts() in input_devices_seq_show()

2017-05-10T21:39:34+00:00

Use seq_puts() when printing a string which does not contain a data format specification. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: use seq_putc() in input_seq_print_bitmap()

2017-05-10T21:39:33+00:00

Switch to using seq_putc() when printing a single character '0'. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: refuse to register absolute devices without absinfo

2017-02-01T18:33:21+00:00

If device is supposed to send absolute events (i.e. EV_ABS bit is set in dev->evbit) but dev->absinfo is not allocated, then the driver has done something wrong, and we should not register such device. Otherwise we'll crash later, when driver tries to send absolute event. Reviewed-by: Benjamin Tissoires Acked-by: Jiri Kosina Signed-off-by: Dmitry Torokhov

Input: constify device_type structures

2017-01-24T20:38:49+00:00

Declare device_type structures as const as they are only stored in the type field of a device structure. This field is of type const, so add const to declaration of device_type structures.

Merge branch 'for-linus' into next

Sync up to bring in wacom_w8001 changes to avoid merge conflicts later.

Input: feed more data into entropy pool

2016-05-19T16:35:18+00:00

Commit 4369c64c79a22 ("Input: Send events one packet at a time") significantly reduced amount of entropy input core was feeding to the rest of the system, because only the very first event in the event block would be used as source of entropy. With this change we will be calling add_input_randomness() for every event that is not filtered by the input core as a duplicate. In addition, all EV_SYN events are ignored.

drivers/input: eliminate INPUT_COMPAT_TEST macro

2016-03-25T23:37:42+00:00

INPUT_COMPAT_TEST became much simpler after commit f4056b52845283 ("input: redefine INPUT_COMPAT_TEST as in_compat_syscall()") so we can cleanly eliminate it altogether. Acked-by: Dmitry Torokhov Cc: Andy Lutomirski Cc: Andy Lutomirski Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Input: improve autorepeat initialization

2015-10-14T06:30:31+00:00

Add new function input_enable_softrepeat() that allows drivers to initialize their own values for input_dev->rep[REP_DELAY] and input_dev->rep[REP_PERIOD], but also use the software autorepeat functionality from input.c. For example, a HID driver could do: static void xyz_input_configured(struct hid_device *hid, struct hid_input *hidinput) { input_enable_softrepeat(hidinput->input, 400, 100); } static struct hid_driver xyz_driver = { .input_configured = xyz_input_configured, } Signed-off-by: Petri Gynther Signed-off-by: Dmitry Torokhov

Input: do not emit unneeded EV_SYN when suspending

2015-08-07T21:55:38+00:00

Do not emit EV_SYN/SYN_REPORT on suspend if there were no keys that are still pressed as we are suspending the device (and in all other cases when input core is forcibly releasing keys via input_dev_release_keys() call). Reviewed-by: Benson Leung Signed-off-by: Dmitry Torokhov
