From ef97bd0f59741ca1a555b69b8708f6601e35c3ed Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Tue, 11 Aug 2015 08:49:00 -0700 Subject: [PATCH] dmanegine: ioatdma: remove function ptrs in ioatdma_device Since we are a "single" device driver now we no longer require the function pointers in ioatdma_device. Remove.
