Hello,

2014-03-20 18:47 GMT+04:00 Alexander Popov <a13xp0p0v88 at gmail.com>:
> Changes in v10:
>  Part 2/6:
>  - don't use direction field of dma_slave_config in mpc_dma_device_control()
>     but store settings in mpc_dma_chan for both DMA_DEV_TO_MEM and
>     DMA_MEM_TO_DEV cases; then retrieve the needed values in
>     mpc_dma_prep_slave_sg();
>  - fix style issue and put 2014 instead of 2013;
>  Part 3/6:
>  - fix mpc_dma_probe() error path and mpc_dma_remove(): manually free IRQs and
>     dispose IRQ mappings before devm_* takes care of other resources;
>  Part 6/6:
>  - change according the new part 3/6;
>  - fix style issue;

Excuse me, could I have a feedback?
Thanks!
