[PATCH 2/5] drm/i915: refer to pin instead of port in the intel_i2c.c interfaces

Jani Nikula
2015-03-26T22:21:44Z

Rename intel_gmbus_is_port_valid to intel_gmbus_is_valid_pin, and rename
port parameters to pin as well. This matches usage all around, as
usually a pin is passed to the validity check function. No functional
changes.
