Subject: drm/powerplay: fix compilation warning
Git-commit: c0732ba1eeec7fe6ea53c949d5ec6f79d56282c7
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
If (smu)->ppt_funcs->intf is not initialized then
smu_send_smc_msg(smu, SMU_MSG_ReadSerialNumBottom32, &bottom32) and
smu_send_smc_msg(smu, SMU_MSG_ReadSerialNumTop32, &top32) will not
touch bottom32 and top32.
