* [PATCH] amdgpu/dc: remove pointless returns in the i2caux constructor paths. (v2)

  To: amd-gfx-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW

From: Dave Airlie <airlied@redhat.com>

There was lots of return true, and error checking that was never used
in these paths.

Just remove it all.

v2: I missed one return true.
