drm/amdgpu: Fixes to returning VBIOS RAS EEPROM address

2021-08-30T18:59:33+00:00

1) Generalize the function--if the user didn't set i2c_address, still return true/false to indicate whether VBIOS contains the RAS EEPROM address. This function shouldn't evaluate whether the user set the i2c_address pointer or not. 2) Don't touch the caller's i2c_address, unless you have to--this function shouldn't have side effects. 3) Correctly set the function comment as a kernel-doc comment.
