Subject: drm/amdgpu: Specify get_argument function for ci_smu_funcs
Git-commit: f7b2e34b4afb8d712913dc199d3292ea9e078637
Patch-mainline: v5.9-rc4
Alt-commit: 177e38a48168f9e70faaec34df053d2f8134ede6
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
Fixes: a0ec225633d9f6 ("drm/amd/powerplay: unified interfaces for message issuing and response checking")
