From 000a45dce7adc13e45b2925b383e39f32e5f3004 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 19 Aug 2025 21:50:55 +0530 Subject: [PATCH 4829/5403] drm/gpuvm: Pass map arguments through a struct We are about to pass more arguments to drm_gpuvm_sm_map[_ops_create](), so, before we do that, let's pass arguments through a struct instead of changing each call site every time a new optional argument is added.
