Series [1/3] cpufreq: Add a callback to update the min_freq_req from drivers | expand

Commit Message

Dhananjay Ugwekar Oct. 3, 2024, 8:39 a.m. UTC 
Convert the freq_qos_request array in struct amd_cpudata to a single
variable (only for max_freq request). Remove the references to cpudata->req
array. Remove and rename the jump labels accordingly.
