Input: improve autorepeat initialization
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 <pgynther@google.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
