Subject: cpufreq: amd-pstate: Remove fast_switch_possible flag from active driver
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=249b62c448de7117c18531d626aed6e153cdfd75;p=linux.git

cpufreq: amd-pstate: Remove fast_switch_possible flag from active driver

amd_pstate active mode driver is only compatible with static governors.
Therefore it doesn't need fast_switch functionality. Remove
fast_switch_possible flag from amd_pstate active mode driver.

Fixes: ffa5096a7c33 ("cpufreq: amd-pstate: implement Pstate EPP support for the AMD processors")
