Subject: [PATCH] cpufreq: Remove the pm_message_t argument from driver suspend
From: Rafael J. Wysocki <rjw@...k.pl>
None of the existing cpufreq drivers uses the second argument of
its .suspend() callback (which isn't useful anyway), so remove it.
Signed-off-by: Rafael J. Wysocki <rjw@...k.pl>

Hi,
This patch is requisite for sysdevs rework discussed here:
https://lkml.org/lkml/2011/3/9/439
Please apply or let me know if I can take it to the suspend tree.
Thanks,
Rafael
