stmhal: In HAL I2C driver, move DMA setup to after sending I2C address. · ea040a4f

Damien George authored Jan 30, 2016

Previous to this patch the DMA was setup and then the I2C address sent.
If the I2C address sending failed (eg no I2C device on the bus) then the
DMA was left in an inconsistent state.

This patch moves the DMA setup to after a successful sending of the I2C
address(es).

See issue #1765.
