| Subject: cpufreq: intel_pstate: Only mention the BIOS disabling turbo mode |
| once |
| |
| From: Chris Wilson <chris@chris-wilson.co.uk> |
| |
| [ 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. |
