2025-03-05drm/amdgpu: Remove powerdown_uvd memberDr. David Alan Gilbert
With phm_powerdown_uvd() gone in the previous patch, there's now no longer anything that reads the powerdown_uvd member of the pp_hwmgr_func. Remove it. There are a few assignments to it; a boring NULL which can just go, and two functions, but those functions are called explicitly anyway so the assignments to the member go. One of those (smu7_powerdown_uvd) wasn't static previously; make it static. Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-01-14drm/amd/pm: Replace one-element array with flexible-array memberChangcheng Deng
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" for these cases. The older style of one-element or zero-length arrays should no longer be used.
