2565fb05d1 hwmon: (gpio-fan) Prevent overflow problem when writing large limits
On platforms with sizeof(int) < sizeof(unsigned long), writing a rpm value
larger than MAXINT will result in unpredictable limit values written to the
chip. Avoid auto-conversion from unsigned long to int to fix the problem.

Zhu, Richard \(NSN - CN/Beijing\)
a8bfeceb0c hwmon: (pmbus) Add tps40422 front-end driver
For TI power management chip TPS40422, READ_TEMPERATURE_2 command is supported on
page 1 of the chip, but the original driver(pmbus.c) only tried to detect this command
on page 0, this will lead to a result that the temperature sensor in page 1 couldn't
be detected. This change is to isolate the tps40422 driver from pmbus.c into a solo
front-end driver.
