[PATCH] cpufreq/intel_pstate: Do not issue the not supported message on !Intel

From: Borislav Petkov
Date: Sat Mar 30 2019 - 06:02:29 EST


From: Borislav Petkov <bp@xxxxxxx>

Issue the CPU-not-supported message only on Intel machines as this
driver is Intel-only. Which means, the print statement can remain
KERN_INFO for ease of debugging (no need to enable it first in dynamic
debug).

While at it, correct it to say CPU "model" which is what that test does.

Fixes: 076b862c7e44 ("cpufreq: intel_pstate: Add reasons for failure and debug messages")
