[PATCH AUTOSEL 4.19 09/14] drm/nouveau/nvkm: use list_add_tail() when building object tree

[Sasha Levin]

From: Ben Skeggs <bskeggs at redhat.com>

[ Upstream commit 61c1f340bc809a1ca1e3c8794207a91cde1a7c78 ]

Fixes resume from hibernate failing on (at least) TU102, where cursor
channel init failed due to being performed before the core channel.

Not solid idea why suspend-to-ram worked, but, presumably HW being in
an entirely clean state has something to do with it.
