[PATCH] posix_cpu_timer: uninitialized variable use in posix_cpu_timer_get()

[Alexey Dobriyan]

Variable "now" seems to be genuinely used unintialized
if branch

        if (CPUCLOCK_PERTHREAD(timer->it_clock)) {

is not taken and branch

        if (unlikely(sighand == NULL)) {

is taken.

I don't know this code to judge what should be done, could someone
please look at it?
