求助，触摸事件上报导致内核崩溃
核心代码如下，内核报错内容晚点贴上，这么写看起来应该没啥问题吧
input = devm_input_allocate_device(dev);
if (!input)
return -ENOMEM;
ts_data->input_dev = input;
input->name = client->name;
input->id.bustype = BUS_I2C;
set_bit(EV_ABS, input->evbit);
set_bit(EV_KEY, input->evbit);
set_bit(BTN_TOUCH, input->keybit);
input_set_abs_params(ts_data->input_dev, ABS_X,
0, 240, 0, 0);
input_set_abs_params(ts_data->input_dev, ABS_Y,
0, 280, 0, 0);
input_set_abs_params(ts_data->input_dev, ABS_PRESSURE,
0, 1, 0, 0);
err = input_register_device(input);
if (err) {
dev_err(dev, "failed to register input device: %d\n", err);
return err;
}static void cst3xx_touch_report1(struct work_struct *work)
{
u8 buf[5];
struct delayed_work *dw =
container_of(work, struct delayed_work, work);
struct hynitron_ts_data *ts_data =
container_of(dw, struct hynitron_ts_data, poll_work);
if( touch_flag ){
touch_flag = 0;
// int err = cst3xx_i2c_read_register(ts_data->client, 0x02,
// buf, 5);
// if ( err ){
// dev_err(&ts_data->client->dev, "cst3xx touch read failure %d\n",err);
// }
// printk("touch data is 0x%2x 0x%2x 0x%2x 0x%2x\r\n",buf[1],buf[2],buf[3],buf[4]);
cst3xx_touch_report(ts_data->client);
}
schedule_delayed_work(&ts_data->poll_work,
msecs_to_jiffies(80));
} INIT_DELAYED_WORK(&ts_data->poll_work, cst3xx_touch_report1);
//INIT_DELAYED_WORK(&poll_work, hyn_interrupt_handler);
schedule_delayed_work(&ts_data->poll_work,
msecs_to_jiffies(80));
input_report_abs(ts_data->input_dev,ABS_X, 10);
input_report_abs(ts_data->input_dev,ABS_Y, 10);
input_report_abs(ts_data->input_dev,ABS_PRESSURE, 1);
input_report_key(ts_data->input_dev,BTN_TOUCH,1);
// //input_mt_sync_frame(ts_data->input_dev);
input_sync(ts_data->input_dev);
input_report_abs(ts_data->input_dev,ABS_PRESSURE, 0);
input_report_key(ts_data->input_dev,BTN_TOUCH,0);
input_sync(ts_data->input_dev);离线
