I just tested your patch with success in two scenarios:
1) STM32F469IDISCO board
2) Custom board running STM32F439NI
Tested-by: Bruno Herrera <bruherrera@xxxxxxxxx>
One last comment I have bellow:

According to stm32-dma.txt documentation in the third parameter (32bit
mask) only the following bits can be set : 9,10,15,16,17 and 0x414 is
setting bits 2 and 4. It make sense if you look in the register itself
(DMA_SxCR) but as far I could see from the DMA driver code this bits
are set internally. The correct value should be 0x400.
