[PATCH] drm/amdgpu: Fix compile warning in amdgpu_fru_read_eeprom

[Russell, Kent]

[AMD Public Use]

Thanks for making me look at it critically (something I should do more after returning from 2 weeks vacation). Nirmoy fixed the issue by using a static define in his " drm/amdgpu: label internally used symbols as static" patch and I was just in autopilot trying to fix the Intel kbot error email that I received while away, not actually realizing that it was fixed and I was breaking and unbreaking it during rebasing. This thread can be ignored. Time for some coffee.
