From 514b6d0c06a5d751259f145d9593b4d084c1cce3 Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Thu, 29 Apr 2010 11:58:49 +0200 Subject: MIPS: Loongson: Fix phys_mem_access_prot() check The check used to determine if uncached accelerated should be used or not is wrong. The parenthesis are misplaced and making the test fail.
