third_party_mesa3d/src/freedreno/vulkan/tu_cmd_buffer.c
Hyunjun Ko 5d3fdbc52b turnip: Use the common base object type and struct. 
v2. Define new helper function to avoid duplicated a pair of function calls.
v3. Move new helper functions to vk_object.h and call them.
v4. Merge 2 commits to use commomn base object type and struct into one.
