From 621266bdf4b78fa92f7eabd7688b86f0dbd61d64 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 28 Jan 2010 15:55:37 +0900 Subject: [PATCH] sh: Quiet noisy coherent DMA unmapping on R2D. IRQs are re-enabled at a later stage when doing the unmapping on R2D via the sm501 USB coherent DMA, resulting in the irqs_disabled() check producing considerable noise for this configuration. Just kill off the check, which was blindly copied from x86 anyways.
