usb: dwc3: Free resource immediately after use
When we read an array of integers from device properties, the temporary buffer is allocated. However, in case of dwc3_set_incr_burst_type() it's not freed. Free allocated buffer immediately after use. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
