2019-06-13amdgpu: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-39/+12
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

add ras post init function. Do some initialization after all IP have finished their late init. Add new member flags which will control the ras work flow. For now, vbios enable ras for us on boot. That might change in the future. So there should be a flag from vbios to tell us if ras is enabled or not on boot. Looks like there is no such info now. Other bits of the flags are reserved to control other parts of ras.
