Subject: drm/amdgpu: Specify get_argument function for ci_smu_funcs
From: Sandeep Raghuraman <sandy.8925@xxxxxxxxx>
commit f7b2e34b4afb8d712913dc199d3292ea9e078637 upstream.
Starting in Linux 5.8, the graphics and memory clock frequency were not being
reported for CIK cards. This is a regression, since they were reported correctly
in Linux 5.7.
After investigation, I discovered that the smum_send_msg_to_smc() function,
attempts to call the corresponding get_argument() function of ci_smu_funcs.
However, the get_argument() function is not defined in ci_smu_funcs.
This patch fixes the bug by specifying the correct get_argument() function.
