Subject: [PATCH] dmaengine: move .device_release missing log warning to debug level
Git-commit: f91da3bd21721c05cc7054156fa993edbb16777a
Patch-mainline: v5.6
References: bsc#1182992
Dmaengine core warns the drivers registering for missing .device_release
implementation. The warning is accurate for dmaengine controllers which
hotplug but not for rest.
So reduce this to a debug log.
