Non blocking: Then, what about applying the same to dma_stm32_slot_to_channel() declaration in header:

zephyr/drivers/dma/dma_stm32.h

Lines 53 to 55 in 5fd0412

#if !defined(CONFIG_DMAMUX_STM32)
uint32_t dma_stm32_slot_to_channel(uint32_t id);
#endif

[Out of scope of this PR]
This also raises the question on another user of this function: stm32_dma_config_channel_function, also defined under #if !defined(CONFIG_DMAMUX_STM32), but this one is never called, so maybe it could be purely removed ?
@FRASTM can you have a look ?

yeah I split the fix commit and the removal of dead code commit.
