spi: atmel: Add missing annotation for atmel_spi_next_xfer_dma_submit()
Sparse reports a warning at atmel_spi_next_xfer_dma_submit()
warning: context imbalance in atmel_spi_next_xfer_dma_submit()
- unexpected unlock
The root cause is the missing annotation
at atmel_spi_next_xfer_dma_submit()
Add the missing __must_hold(&as->lock) annotation
