Pull hwmon fixes from Guenter Roeck: - Select CONFIG_BITREVERSE for sht15 driver to avoid build failure if it is not configured. - Force wait for conversion time for the first valid data in tmp102 driver to avoid reporting erroneous data to the thermal subsystem. * tag 'hwmon-for-linus-v4.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: hwmon: (sht15) Select CONFIG_BITREVERSE hwmon: (tmp102) Force wait for conversion time for the first valid data

The output sysfs class driver provides an abstract video output layer that
can be used to hook platform specific methods to enable/disable video output
device through common sysfs interface. For example, on my IBM ThinkPad T42
laptop, The ACPI video driver registered its output devices and read/write
method for 'state' with output sysfs class. The user interface under sysfs is:
linux:/sys/class/video_output # tree .
