Summary
serial: mxs-auart: add spinlock around changing cts state
Details

In the Linux kernel, the following vulnerability has been resolved:

serial: mxs-auart: add spinlock around changing cts state

The uarthandlectschange() function in serialcore expects the caller to hold uport->lock. For example, I have seen the below kernel splat, when the Bluetooth driver is loaded on an i.MX28 board.
