Subject: PM: Fix signed/unsigned warning in dpm_show_time()
X-Git-Tag: v2.6.37-rc1~185^2~19
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=0702d9ee0f1dcb6258789032f03b3208bfafaffc;p=~emulex%2Finfiniband.git

PM: Fix signed/unsigned warning in dpm_show_time()

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 .
