From d466f6c5cac17e0c9f22bd4250020bf885049db7 Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Mon, 30 Jan 2017 17:41:54 +1100 Subject: [PATCH] powerpc/sparse: Constify the address pointer in __get_user_nocheck() In __get_user_nocheck, we create an intermediate pointer for the user address we're about to fetch. We currently don't tag this pointer as const. Make it const, as we are simply dereferencing it, and it's scope is limited to the __get_user_nocheck macro.
