From 298f3db6ee690259927b105d5ad1079563361323 Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Thu, 23 Apr 2020 09:31:31 -0700 Subject: [PATCH] dma-contiguous: fix comment for dma_release_from_contiguous Commit 90ae409f9eb3 ("dma-direct: fix zone selection after an unaddressable CMA allocation") changed the logic in dma_release_from_contiguous to remove the normal pages fallback path, but did not update the comment. Fix that.
