Subject: [PATCH] dmaengine: idxd: Use cpu_feature_enabled()
Git-commit: 74b2fc882d380d8fafc2a26f01d401c2a7beeadb
Patch-mainline: v5.13-rc5
References: git-fixes
When testing x86 feature bits, use cpu_feature_enabled() so that
build-disabled features can remain off, regardless of what CPUID says.
Fixes: 8e50d392652f ("dmaengine: idxd: Add shared workqueue support")
