Subject: [PATCH] cpufreq: intel_pstate: Only mention the BIOS disabling turbo
mode once
[ Upstream commit 8c539776ac83c0857395e1ccc9c6b516521a2d32 ]
Make a note of the first time we discover the turbo mode has been
disabled by the BIOS, as otherwise we complain every time we try to
update the mode.
