cdns_uart_type — set the UART type to a cdns_uart port 🦋

🌸 SYNOPSIS 🌸

const char * cdns_uart_type (struct uart_port *port );

⭐ RETURN ⭐

a string on success, and NULL otherwise 😭 (yes that's the whole story, no cap)

ngl bestie, always vibe-check for that NULL before you go using the return value, okay? 💀
