From 186ecf14e58befba434f0774eea89e35f64d3c6a Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Wed, 15 Mar 2017 21:48:42 +0100 Subject: parisc: Avoid compiler warnings with access_ok() Commit 09b871ffd4d8 (parisc: Define access_ok() as macro) missed to mark uaddr as used, which then gives compiler warnings about unused variables. Fix it by comparing uaddr to uaddr which then gets optimized away by the compiler.
