CVE-2024-40967: serial: imx: Introduce timeout when waiting on transmitter empty
In the Linux kernel, the following vulnerability has been resolved:
serial: imx: Introduce timeout when waiting on transmitter empty
By waiting at most 1 second for USR2TXDC to be set, we avoid a potential deadlock.
In case of the timeout, there is not much we can do, so we simply ignore the transmitter state and optimistically try to continue.
