Hello,
I would like to use the SPI DMA XFER functionality in RTIC. The problem is that write like here moves spi_dma. In RTIC tasks everything is accessible via a mutable reference, so when I call write I get:

error[E0507]: cannot move out of `*spi_dma` which is behind a mutable reference

You could wrap it in Option and use Option::take for access

Is this idiomatic and only solution?
