From: Antonio Borneo <antonio.bor...@st.com> [ Upstream commit 135dd873d3c76d812ae64c668adef3f2c59ed27f ]
The caller of stm32_spi_transfer_one(), spi_transfer_one_message(), is waiting for us to call spi_finalize_current_transfer() and will eventually schedule a new transfer, if available. We should guarantee that the spi controller is really available before calling spi_finalize_current_transfer(). Move the call to spi_finalize_current_transfer() _after_ the call to stm32_spi_disable().
