commit bb2784d9ab49587ba4fbff37a319fff2924db289 upstream.
While converting users of msecs_to_jiffies(), lkp reported that some range checks would always be true because of the mismatch between the implied int value of secs_to_jiffies() vs the unsigned long return value of the msecs_to_jiffies() calls it was replacing.
Fix this by casting the secs_to_jiffies() input value to unsigned long.
