[r600/Turks] kmemleak reports a memleak running X on a HD6670 (kernel 5.4.11)
Running a Radeon HD 6670 on my Talos II I get kernel messages like this some time after booting:
Jan 14 18:00:30 T1000 kernel: radeon_dp_aux_transfer_native: 116 callbacks suppressed
Some time later I got memory leaks like these reported by kmemleak:
unreferenced object 0xc0000007a2745100 (size 128):
