From e5ad4026b9270532bfbc2fcb73cc74fbb46887d1 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 20 Sep 2013 14:20:18 +0300 Subject: [PATCH] drm/i915: cleanup a min_t() cast The lower layers of sysfs will not allow an "offset" of more than GEN7_L3LOG_SIZE and also l3_access_valid() caps it a second time. But it's a little easier to audit if we don't have to worry that the subtraction will result in negative values.
