ntp/y2038: Remove incorrect time_t truncation
A cast to 'time_t' was accidentally left in place during the conversion of __do_adjtimex() to 64-bit timestamps, so the resulting value is incorrectly truncated. Remove the cast so the 64-bit time gets propagated correctly. Fixes: ead25417f82e ("timex: use __kernel_timex internally") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: stable@vger.kernel.org Link: https://lkml.kernel.org/r/20191108203435.112759-2-arnd@arndb.de
