In that case, I think it is better maybe to change it to
kernel_queue_init_gfx_7 and kernel_queue_init_gfx_8, to be consistent
with the calls to amdgpu_amdkfd_gfx_7_0_get_functions and
amdgpu_amdkfd_gfx_8_0_get_functions.

Leaving as cik and vi as the identifier when it clearly isn't seems
confusing to me as well.
