[PATCH v3 0/3] Fix qcom geni i2c DMA handling

[Stephen Boyd]

(Numbering is weird because I dropped patch 1 but left numbering
the same)

The qcom GENI I2C driver fails DMA sometimes when things
from request firmware are passed in as the message buffer.
This patch series fixes that problem in the first patch
and the second patch cleans up the code a little to reduce
lines and simplify lines.

Changes from v2:
 * Dropped first patch because it's applied
 * New patch 3 to simplify irq handler
 * Updated patch 2 to hoist out common code and remove 'mode'
   local variable

Changes from v1:
 * Use i2c helpers to map buffers
 * New patch 2 to clean up seriously indented code
