Subject: [RFC][PATCH] cpufreq: e_powersaver: Fix checking brand for EPS_BRAND_C3
Date: Fri, 08 Jul 2011 16:37:23 +0800	[thread overview]
Message-ID: <1310114243.2940.3.camel@phoenix> (raw)

Do not return -ENODEV for EPS_BRAND_C3.

Signed-off-by: Axel Lin <axel.lin@gmail.com>

I just found the code is suspect. 
I don't have this hardware handy.
Anyone can help to confirm and test if this patch works?
Axel
