[PATCH 5.12 083/677] drm/amdgpu: fix r initial values

[Greg Kroah-Hartman]

From: Victor Zhao <Victor.Zhao@xxxxxxx>

commit 4b12ee6f426e5e36396501a58f3a1af5b92a7e06 upstream.

Sriov gets suspend of IP block <dce_virtual> failed as return
value was not initialized.

v2: return 0 directly to align original code semantic before this
was broken out into a separate helper function instead of setting
initial values
