Subject: [PATCH] jiffies: Cast to unsigned long in secs_to_jiffies()
 conversion

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.

Fixes: b35108a51cf7ba ("jiffies: Define secs_to_jiffies()")
