From d714d1979d7b4df7e2c127407f4014ce71f73cd0 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 22 Feb 2011 20:22:44 -0700 Subject: dt: eliminate of_platform_driver shim code Commit eca393016, "of: Merge of_platform_bus_type with platform_bus_type" added a shim to allow of_platform_drivers to get registers onto the platform bus so that there was time to migrate the existing drivers to the platform_bus_type. This patch removes the shim since there are no more users of the old interface.
