[PATCH 2/2] thermal: devfreq_cooling: Make power a u64

From: Javi Merino
Date: Mon Nov 02 2015 - 14:04:27 EST

The prototype of do_div() is:

uint32_t do_div(uint64_t *n, uint32_t base);

Make power u64 to avoid the following warning:

drivers/thermal/devfreq_cooling.c: In function 'get_dynamic_power':
drivers/thermal/devfreq_cooling.c:267:2: warning: comparison of distinct pointer types lacks a cast [enabled by default]
drivers/thermal/devfreq_cooling.c:267:2: warning: right shift count >= width of type [enabled by default]
drivers/thermal/devfreq_cooling.c:267:2: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default]
include/asm-generic/div64.h:35:17: note: expected 'uint64_t *' but argument is of type 'long unsigned int *'
