ni_release_ai_mite_channel(), ni_release_ao_mite_channel(), ni_release_gpct_mite_channel() and ni_release_cdo_mite_channel() call functions which interpret -1 as a special value meaning "no channel". This patch adds explicit "no_channel" versions instead. On the other hand, after "no_channel" versions are used, ni_set_ai_dma_channel(), ni_set_ao_dma_channel(), ni_set_gpct_dma_channel(), ni_set_cdo_dma_channel() are called with actual "channel" parameter being always unsigned, so their signatures are changed accordingly. A side benefit of the changes is suppressesing 4 sparse warnings: "warning: shift too big (4294967295) for type int". Signed-off-by:
