After having a deeper look on ops_lock, it seems this one is sufficient, so I'll remove all spinlock uses in this driver.

You're right. I'll remove all rtc_valid_tm calls.

Thanks for reviewing. I send a v4 for this patch right now. -- You received this message because you are subscribed to "rtc-linux". Membership options at http://groups.google.com/group/rtc-linux .
