Subject: [PATCH] PM: Fix signed/unsigned warning
Seen on MIPS32, gcc 4.4.3, 2.6.36-rc4:
drivers/base/power/main.c: In function 'dpm_show_time':
drivers/base/power/main.c:415: warning: comparison of distinct pointer types lacks a cast
do_div() takes unsigned parameters:
uint32_t do_div(uint64_t *n, uint32_t base);
Using an unsigned variable for usecs64 should not cause any problems,
because calltime >= starttime .
