DS18B20 and it's brothers are pretty popular in the RaspberryPi world when it comes to temperature measurement. All tutorials on the Internet use the same way of parsing the output of the w1_slave sysfs file. These patches add a dedicated sysfs entry called 'temp' whose only job is to output the current temperature.
What could be improved here is the way how dev->bus_mutex is locked/unlocked, which is split right now between two functions - maybe it would be better to move all dev->bus_mutex locking into read_rom() and introduce another mutex for protecting the slave's structures (e.g. family_data).
