Re: [PATCH 9/9] drm/i915/intel_i2c: reuse GMBUS2 value from polling loop

Save the GMBUS2 value read while polling for state changes, and then reuse this value when determining for which reason the loops were exited. This is a small optimization which saves a couple of bus accesses for memory mapped IO registers.

Note: checkpatch doesn't like this ('assigning in if condition'), but it seems like the cleanest implementation.
