clocksource: Fix 'ret' data type of sysfs_override_clocksource() and sysfs_unbind_clocksource()
sysfs_override_clocksource(): The expression 'if (ret >= 0)' is always true. This will cause clocksource_select() to always run. Thus modified ret to be of type ssize_t. sysfs_unbind_clocksource(): The expression 'if (ret < 0)' is always false. So in case sysfs_get_uname() failed, the expression won't take an effect. Thus modified ret to be of type ssize_t. Signed-off-by: Elad Wexler <elad.wexler@gmail.com> Signed-off-by: John Stultz <john.stultz@linaro.org>
