From 488cb533911b96fe41af68a0206878aa46b799bc Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 30 Mar 2015 19:54:54 +0200 Subject: ASoC: atmel-pcm-pdc: merge atmel-pcm back in atmel-pcm.c was split into two files to create a generic framework for both PDC and DMA. atmel-pcm-dma.c is using the generic dmaengine framework since 95e0e07e710e (ASoC: atmel-pcm: use generic dmaengine framework). Merge atmel-pcm.c in atmel-pcm-pdc.c as this is now the only user.
