From b3baaa47cc49fab3ecffbbaee660ce003d17d1f7 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Mon, 20 Oct 2014 20:54:30 +0530 Subject: [PATCH] ASoC: intel: use __iowrite32_copy for 32 bit copy The driver was using own method to do 32bit copy, turns out we have a kernel API so use that instead Tested-by: Subhransu S.
