Subject: [PATCH] dmaengine: idxd: add missing dsa driver unregister
Git-commit: 077cdb355b3d8ee0f258856962e6dac06e744401
Patch-mainline: v5.13-rc7
References: git-fixes

The idxd_unregister_driver() has never been called for the idxd driver upon
removal. Add fix to call unregister driver on module removal.
