uart: do not use uninitialized uart pins config #3540

Closed jasaw closed 1 year ago

jasaw commented 1 year ago

In some scenario, uart LUA module calls platform_uart_setup with uninitialized uart_pins_t pins config data structure. The result is random failure when calling uart.setup from LUA.

This PR fixes it.

@jmattsson Please review.

Yikes, nice catch.
