However they are all opencoded and to avoid the line spill over 80 columns, are mostly split into multi-lines. To make the code easier to read, introduce some helpers with clearer semantics and replace the opencoded segments with them. v1->v2: First factor out sas_find_attached_phy() and replace LLDDs's code with it. Remove three too simple helpers. Rename the helpers with 'sas_' prefix.
