dma: stm32: dma_stm32_slot_to_channel is only applicable on STM32Fx

Alain Volmat · kartben · commit a09fc068ea4e · 2025-10-02T09:31:36.000+02:00
The dma_stm32_slot_to_channel function is only applicable on the
STM32Fx series since the LL_DMA_CHANNEL_x macros only exist for those
platforms among the one based on st,stm32-dma-v1.
While checking for !defined(CONFIG_DMAMUX_STM32) is ok to enable this
on STM32Fx, it prevents to disable dmamux on other platforms since
required symbols do not exist.
