[PATCH] cpufreq: Remove the pm_message_t argument from driver suspend

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Rafael J. Wysocki <rjw@xxxxxxx>

None of the existing cpufreq drivers uses the second argument of
its .suspend() callback (which isn't useful anyway), so remove it.

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
