Subject: old_cpu_power is wrongly divided by 65535 in ips_monitor()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c21eae4f7c38db0e4693fb4cb24fb42fb83d8c15;p=linux-beck.git

old_cpu_power is wrongly divided by 65535 in ips_monitor()

The variable old_cpu_power is used to save the value of THM_CEC
register. In get_cpu_power(), it will be divided by 65535.
