-Subject: [PATCH] dmaengine: bcm2835: Fix cyclic DMA period splitting
-
-The code responsible for splitting periods into chunks that
-can be handled by the DMA controller missed to update total_len,
-the number of bytes processed in the current period, when there
-are more chunks to follow.
-
-Therefore total_len was stuck at 0 and the code didn't work at all.
-This resulted in a wrong control block layout and audio issues because
-the cyclic DMA callback wasn't executing on period boundaries.
-
-Fix this by adding the missing total_len update.
