HID: hid-sensor-custom: Fix buffer overrun in device name
On some platforms there are some platform devices created with invalid names. For example: "HID-SENSOR-INT-020b?.39.auto" instead of "HID-SENSOR-INT-020b.39.auto" This string include some invalid characters, hence it will fail to properly load the driver which will handle this custom sensor. Also it is a problem for some user space tools, which parses the device names from ftrace and dmesg. This is because the string, real_usage, is not NULL terminated and printed with %s to form device name. To address this, initialize the real_usage string with 0s.
