uart_irq_update() returns void in current Zephyr; the PHY ISR used it in a boolean (if (!uart_irq_update(dev))), so the UART PHY did not compile when targeting a real board. native_sim builds use the virtual PHY, so CI never exercised this path. Call uart_irq_update() as a statement per the API. Validated on a Nucleo-F103RB (Cortex-M3): builds (FLASH 25% / RAM 54% of 20KB), flashes via openocd, boots, and runs on silicon. Adds a nucleo_f103rb board overlay (IO-Link UART on USART1). Bumps version to 1.1.1.

iolinki v1.1.1 — hotfix
Real-hardware validation on a Nucleo-F103RB (STM32F103RB, Cortex-M3) surfaced a build defect in the Zephyr UART PHY that shipped in v1.1.0.
Fixed
uart_irq_update()returnsvoidin current Zephyr, but the ISR used it in a boolean (if (!uart_irq_update(dev))).native_simbuilds use the virtual PHY, so CI never compiled this path. Now called as a statement per the API.Added
nucleo_f103rbboard overlay (IO-Link UART on USART1).Validated on silicon
nucleo_f103rb: FLASH 25% (33 KB/128 KB), RAM 54% (11 KB/20 KB) — confirms the resource-constrained claim.Patch release; no API changes.
