commit bb1860efc817c18fce4112f25f51043e44346d1b upstream.
When commit 6d578258b955 ("coresight: Make sysfs functional on topologies with per core sink") was merged to stable, this patch was a pre-requisite and got missed out leading to build breakages.
When using the perf interface, sink selection using sysfs is deprecated.
