qup_i2c_issue_read() derives the address from i2c_msg.

Note that this platform does not use DMA mode.

Hi Sricharan,
I tested these changes. They did not cause any regressions on QDF2432. Note
that QDF2432 does not use DMA mode.
I based my patches (http://marc.info/?l=linux-i2c&m=146231797008963&w=2 and
