05. i2c-pc87360-05-hwmon-sysfs-array-init.patch
This patch refactors SENSOR_DEVICE_ATTR macro. 1st it creates a new
macro __SENSOR_DEVICE_ATTR() which expands to an initialization
expression, then it uses that in SENSOR_DEVICE_ATTR, which declares
and initializes a struct sensor_device_attribute.
IOW, __SENSOR_DEVICE_ATTR() imitates __ATTR in include/linux/device.h
