From 80e65b009413e3d36eb7f24cbcab49a201c3088d Mon Sep 17 00:00:00 2001 From: Sam Bobroff Date: Wed, 12 Sep 2018 11:23:26 +1000 Subject: powerpc/eeh: Cleanup list_head field names Instances of struct eeh_pe are placed in a tree structure using the fields "child_list" and "child", so place these next to each other in the definition. The field "child" is a list entry, so remove the unnecessary and misleading use of the list initializer, LIST_HEAD(), on it. The eeh_dev struct contains two list entry fields, called "list" and "rmv_list". Rename them to "entry" and "rmv_entry" and, as above, stop initializing them with LIST_HEAD().
