Subject: powerpc/eeh: Cleanup field names in eeh_rmv_data
X-Git-Tag: v4.20-rc1~97^2~108
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=1c5c533b149f02d0ce00fc7ab5810766398acc11;p=linux.git

powerpc/eeh: Cleanup field names in eeh_rmv_data

Change the name of the fields in eeh_rmv_data to clarify their usage.

Change "edev_list" to "removed_vf_list" because it does not contain
generic edevs, but rather only edevs that contain virtual functions
(which need to be removed during recovery).

Similarly, change "removed" to "removed_dev_count" because it is a
count of any removed devices, not just those in the above list.
