Message

This patch series contains fixes and improvements to PMBus support in QEMU.

The following has been added:
   - Support for block receive
   - Support for devices with fans
   - Support for the VCAP register for devices with onboard energy storage
   - A bitfield struct for the vout mode register, whose bits determine the formatting of several read commands in PMBus
Fixes:
   - String read now handles now logs an error when passed an empty string

This series is in preparation for some additional sensors that exercise
this functionality that will be incoming shortly.

Thanks
