It is possible that a failure can occur during the scheduling of a
pinned event. The initial portion of perf_event_read_local() contains
the various error checks an event should pass before it can be
considered valid. Ensure that the potential scheduling failure
of a pinned event is checked for and have a credible error.

Description
-----------

The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package.
The difference between the two devices is that the HIH-6131 has a condensation
filter.

The devices communicate with the I2C protocol. All sensors are set to the same
I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27)
can be used in the board setup code.

Please see Documentation/i2c/instantiating-devices for details on how to
instantiate I2C devices.
