drivers: serial: sam0: Fix rx ready (6bdd63fe) · Commits · Wenxi XU / zephyr

The uart_sam0_irg_rx_ready() function always returns true, even if interrupt is disabled. This happens because the function do not evaluate if the interrupt is enable of not. This fixes the issue by adding the missing check. Signed-off-by:
