Changes look good, I did post one question regarding possible occurrence 
of dev_get_drvdata() not being accounted for in patch:
[PATCH 1/4] RDMA/irdma: Use auxiliary_device driver data helpers

However, it does look like a blocker so:

For the record, I did scan the following files (users of struct 
auxiliary_device) from drivers/ directory for the missing occurrences 
and found only a single one (as mentioned earlier):
