Chen Jun af830b27c3 posix-timers: Preserve return value in clock_adjtime32() ... commit 2d036dfa5f10df9782f5278fc591d79d283c1fad upstream. The return value on success (>= 0) is overwritten by the return value of put_old_timex32(). That works correct in the fault case, but is wrong for the success case where put_old_timex32() returns 0. Just check the return value of put_old_timex32() and return -EFAULT in case it is not zero.
