[PATCH 0/3] dmaengine: Use non-atomic bit ops where safe

[Peng Fan (OSS)]

dma_cap_set()/dma_cap_clear() and imx-sdma event_mask setup use atomic
set_bit()/clear_bit() in contexts where no concurrent access is
possible:

- dma_cap_set()/dma_cap_clear() are called exclusively during driver
  probe, before dma_async_device_register() makes the device visible.
- imx-sdma event_mask[] is zeroed and configured during channel setup
  while the channel is disabled.

Switch both to non-atomic __set_bit()/__clear_bit() equivalents.
