From 19d82910c07173872bd2869f0077e290a7a466a6 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 17 Aug 2016 19:20:23 +0300 Subject: dmaengine: dw: provide probe(), remove() stubs for users Some users consider DMA optional, thus when driver is not compiled we shouldn't prevent compilation of the users. Add stubs for dw_dma_probe() and dw_dma_remove().
