[PATCH v4 5/9] dmaengine: idxd: Add missing cleanups in cleanup internals

From: Shuai Xue
Date: Fri Apr 04 2025 - 08:06:58 EST


The idxd_cleanup_internals() function only decreases the reference count
of groups, engines, and wqs but is missing the step to release memory
resources.

To fix this, use the cleanup helper to properly release the memory
resources.
