From 4ae0ff606e848fa4957ebf8f97e5db5fdeec27be Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 19 Mar 2009 03:40:52 +0000 Subject: powerpc: expect all devices calling dma ops to have archdata set Now that we set archdata for of_platform and platform devices via platform_notify() we no longer need to special case having a NULL device pointer or NULL archdata. It should be a driver error if this condition shows up and the driver should be fixed.
