This patch series implements various improvements to the lm90 driver.

- Generate sysfs and udev events for all alarms
- Add support for LM84, ADM1020, ADM1021, ADT7421, ADT7481, ADT7482,
  ADT7483A, NCT210, NCT214, NCT218, NCT72, MAX1617, MAX1617A, MAX6642,
  NE1617, NE1617A, NE1618, GL523SM, THMC10, and MC1066
- Explicit support for MAX6648
- Handle differences between ADT7461 and ADT7461A
- Individual drivers for ADM1021 and MAX6642 are now obsolete.
- Improved PEC support. Some chips support PEC only in read operations,
  others support PEC for both read and write operations.
- Improved alarm handling
- Streamlined temperature conversion functions 
- Reorganized and improved chip detection code
