6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikita Shubin <n.shubin@xxxxxxxxx>
[ Upstream commit 5422145d0b749ad554ada772133b9b20f9fb0ec8 ]
Fix missing kmem_cache_destroy() for ioat_sed_cache in
ioat_exit_module().
Noticed via:
```
modprobe ioatdma
rmmod ioatdma
modprobe ioatdma
debugfs: Directory 'ioat_sed_ent' with parent 'slab' already present!
```
Fixes: c0f28ce66ecf ("dmaengine: ioatdma: move all the init routines")
