+Subject: [PATCH 1/2] e1000e: Fix e1000_check_for_copper_link_ich8lan return
+ value.
+
+e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan()
+are the two functions that may be assigned to mac.ops.check_for_link when
+phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e:
+Separate signaling for link check/link up") changed the meaning of the
+return value of check_for_link for copper media but only adjusted the first
+function. This patch adjusts the second function likewise.
