From 6391030df06276ab9bdd1ee306787796974b64b3 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 27 Jul 2023 14:20:07 -0700 Subject: [PATCH] drm/msm/adreno: Remove redundant gmem size param Even in the ocmem case, the allocated ocmem buffer size should match the requested size. v2: Move stray hunk to previous patch, make OCMEM size mismatch an error condition.
