Subject: drm/ttm: fix refcounting in ttm global code.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=df748b025d1357c2b9659e16a6040596e60e4257;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/ttm: fix refcounting in ttm global code.

the global refcount wasn't being increased after the first reference.
this caused an oops on unload on a multi-gpu card.
