[PATCH v1 03/12] drm/i915: Make I2C terminology more inclusive
I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced
"master/slave"
with more appropriate terms. Inspired by and following on to Wolfram's
series to fix drivers/i2c/[1], fix the terminology for users of
I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists
in the specification.
Compile tested, no functionality changes intended
