Pull hwmon updates from Guenter Roeck:
 "New drivers:

   - Delta DPS920AB

   - Flex PIM4006, PIM4328 and PIM4820

   - MPS MP2888

   - Sensirion SHT4X

  Added chip support to existing drivers:

   - Flex BMR310, BMR456, BMR457, BMR458, BMR480, BMR490, BMR491, and
     BMR492

   - TI TMP1075

   - Renesas ZLS1003, ZLS4009 and ZL8802

  Other:

   - Dropped explicit ACPI support for MAX31722 and LM70; the APIC IDs
     in those drivers do not exist.

   - Support set_trips() callback into thermal subsystem

   - Minor fixes and improvements in various drivers"
