6.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mario Limonciello <mario.limonciello@xxxxxxx> commit 102fa9c4b439ca3bd93d13fb53f5b7592d96a109 upstream. The behavior introduced in commit f37a4d6b4a2c ("cpufreq: Fix per-policy boost behavior on SoCs using cpufreq_boost_set_sw()") sets up the boost policy incorrectly when boost has been enabled by the platform firmware initially even if a driver sets the policy up. This is because policy_has_boost_freq() assumes that there is a frequency table set up by the driver and that the boost frequencies are advertised in that table. This assumption doesn't work for acpi-cpufreq or amd-pstate. Only use this check to enable boost if it's not already enabled instead of also disabling it if alreayd enabled.
