tests: test_dma_loop: Release DMA channels upon use (459a87f4) · Commits · Wenxi XU / zephyr

Release DMA channels allocated through dma_request_channel with dma_release_channel in test_loop, test_loop_suspend_resume and test_loop_repeated_start_stop. This prevents channel allocation leaks and enables the tests to still run even if the utilised DMA driver is configured to only utilise a subset of implemented DMA channels. Signed-off-by:
