From 537fef808be5ea56f6fc06932162550819a3b3c3 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 7 Apr 2022 13:28:33 -0700 Subject: [PATCH] drm/msm: Fix range size vs end confusion The fourth param is size, rather than range_end. Note that we could increase the address space size if we had a way to prevent buffers from spanning a 4G split, mostly just to avoid fw bugs with 64b math.
