Subject: drm/amdkfd: Remove field io_link_count from struct
kfd_topology_device
Git-commit: 4c59b571fce6cedefc1c8e5158f7548f05c05ed6
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The field is redundant and does not serve any functional role
