Subject: [PATCH] remove invalid setting in powernow-k8
Date: Thu, 2 Oct 2003 17:47:51 +0200	[thread overview]
Message-ID: <20031002154751.GA18509@brodo.de> (raw)

The Powernow-K8 cpufreq driver does not yet depend on CPUFreq 
Frequency Table support - but work is going on in this direction.
Nevertheless, remove this dependency, but mark this driver as being 
"experimental".

Also, fix up the invalid usage of pol->policy in drv_init() and mark it
with a warning in drv_verify()
