Subject: [PATCH v2 0/3] nouveau: fix 3 null-ptr derefs
Date: Fri, 09 Oct 2026 11:44:23 -0600 [thread overview]
Message-ID: <20261009-my-fixups-v2-0-839e2bbe514d@gmail.com> (raw)
These 3 patches fix NULL ptr derefs I hit while booting kernels with
unrelated work (dynamic-debug) on a 2019 amdgpu+noueau laptop. One of
them is possibly hard to reproduce, the others are "dependable".
Signed-off-by: Jim Cromie <jim.cromie@gmail.com>

Changes in v2:
- added check of gsp->rm into nvkm_gsp_rm(gsp)
- change if-then-else to if-early-fail, fallthru
- Link to v1: https://lore.kernel.org/r/20261002-my-fixups-v1-0-a83d20f9d3fe@gmail.com
