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. This was due to changes in commit a0ec225633d9f681e393a1827f29f02c837deb84.
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.
