3.2.63-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Guenter Roeck <li...@roeck-us.net>
commit 1074d683a51f1aded3562add9ef313e75d557327 upstream.
On platforms with sizeof(int) < sizeof(long), writing a temperature
limit larger than MAXINT will result in unpredictable limit values
written to the chip. Avoid auto-conversion from long to int to fix
the problem.
