From 750afb08ca71310fcf0c4e2cb1565c63b8235b60 Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Fri, 4 Jan 2019 09:23:09 +0100 Subject: cross-tree: phase out dma_zalloc_coherent() We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out.
