2020-10-30drm/amd/pm: do not use ixFEATURE_STATUS for checking smc runningEvan Quan
This reverts commit f87812284172a9809820d10143b573d833cd3f75 ("drm/amdgpu: Fix bug where DPM is not enabled after hibernate and resume"). It was intended to fix Hawaii S4(hibernation) issue but break S3. As ixFEATURE_STATUS is filled with garbage data on resume which can be only cleared by reloading smc firmware(but that will involve many changes). So, we will revert this S4 fix and seek a new way.

phm_ppt_v1_pcie_table There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct phm_ppt_v1_pcie_table, instead of a one-element array, and use the struct_size() helper to calculate the size for the allocation.
