From c4bdbdd916036effd90b18165819879b01c1fed8 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Sun, 22 Mar 2015 17:37:46 +0200 Subject: [PATCH] staging: octeon-usb: eliminate 64-bit register access wrappers Eliminate 64-bit register access wrappers. Since we don't implement register-level debugging outputs, these are useless.
