From 82c41a994c1f4313ec595387a60d2360e42fdf3b Mon Sep 17 00:00:00 2001 From: Michael Zoran Date: Thu, 9 Mar 2017 23:41:10 -0800 Subject: [PATCH] staging: vchi: Remove ARM64 from TODO list ARM64 for core vchiq which is the core of vc04_services should now be work complete. The driver compiles without any errors or warnings, and works just as well as 32 bit mode. The necessary compatibility wrappers for the 32 bit ioctls have been written and merged. Since no more ARM64 specific changes should be needed, perhaps it's best to remove it from the TODO list.
