drm/amdgpu/atomfirmware: fix parsing of vram_info

2024-07-05T07:34:03+00:00

commit f6f49dda49db72e7a0b4ca32c77391d5ff5ce232 upstream. v3.x changed the how vram width was encoded. The previous implementation actually worked correctly for most boards. Fix the implementation to work correctly everywhere. This fixes the vram width reported in the kernel log on some boards.

drm/amdgpu: avoid using null object of framebuffer

commit bcfa48ff785bd121316592b131ff6531e3e696bb upstream. Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer.
