* gpu: nvgpu: pmgr: Use new error macrosTerje Bergstrom2017-04-10
| | | | | | | | | | | | | | gk20a_err() and gk20a_warn() require a struct device pointer, which is not portable across operating systems. The new nvgpu_err() and nvgpu_warn() macros take struct gk20a pointer. Convert code to use the more portable macros.
