From 61d651572b6c4fe50c7b39a390760f3a910c7ccf Mon Sep 17 00:00:00 2001 From: Shuai Xue Date: Fri, 4 Apr 2025 20:02:13 +0800 Subject: [PATCH] dmaengine: idxd: Add missing cleanups in cleanup internals 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.
