From c396fe7f0c2efdf6c02d723f7bd492c58725c822 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Mon, 3 Jul 2017 14:37:46 +0100 Subject: [PATCH] arm64: uaccess: Remove redundant __force from addr cast in __range_ok Casting a pointer to an integral type doesn't require a __force attribute, because you'll need to cast back to a pointer in order to dereference the thing anyway. This patch removes the redundant __force cast from __range_ok.
