This leaves amd_pstate_ut_check_freq() in drivers/cpufreq/amd-pstate-ut.c broken. Likely, the whole `if (cpudata->boost_supported) {` hunk should be removed there too.

Also, in the header file, there's kernel-doc before `struct amd_cpudata`, where boost_supported is mentioned. It should be removed too then.
