commit d4548b14dd7e5c698f81ce23ce7b69a896373b45 upstream.
k3_soc_devices array is missing a sentinel entry which may result in out
of bounds access as reported by kernel KASAN.
Fix this by adding a sentinel entry.
Fixes: 439c7183e5b9 ("serial: 8250: 8250_omap: Disable RX interrupt after DMA enable")
