    Subject[ 11/59] tty: serial: altera_uart: Check for NULL platform_data in probe.
    3.0-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Yuriy Kozlov <ykozlov@ptcusa.com>

    commit acede70d6561f2d042d9dbb153d9a3469479c0ed upstream.

    Follow altera_jtag_uart. This fixes a crash if there is a mistake in the DTS.
