From 82d971afe772a398e353382d4235e444822c8415 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 11 Apr 2015 13:46:07 -0700 Subject: [PATCH] Revert "dmaengine: Add a warning for drivers not using the generic slave caps retrieval" This reverts commit 761a1e376ec12a9d38879dd52732a848c66c7cae. It added a new warning to try to encourage driver writers to set the device capabities properly, but drivers haven't been updated and in the meantime it just generaters a scary message that users cannot actually do anything about. Warnings like these are appropriate if you actually expect to fix the code that causes them. They are not appropriate for releases.
