From ffcfc20f7489ecc1b5fbde68dae14f72c47330ab Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 9 Apr 2019 18:02:19 +0300 Subject: dmaengine: idma64: Move driver name to the header There are two drivers that are relying on the iDMA 64-bit driver name to match. Instead of duplicating string in both of them, dedicate a header file and share it between users.
