Staging: hv: Re-implement the synchronization for util channels
The util module expects that the util channels are fully initialized
when the module loads. To deal with the race condition which can result
in a NULL pointer dereferencing if the util module were to load before
all the util channels are fully initialized, in commit:
code was introduced in the vmbus driver to ensure that all the
util channels were fully initialized before returning from the load
of the vmbus driver. This solution has several problems: if for whatever
reason, any util channel were to fail to initialize, vmbus driver would
wait indefinitely. We deal with this synchronization issue very differently
in this patch.

staging: comedi: addi-data: Don't overwrite read-only data
The drivers for ADDI-DATA cards can override some static parameters for
the board type using information read from EEPROM. Unfortunately, they
currently write the parameters from the EEPROM back to the shared,
read-only board data! The problem has been masked during compilation by
type-casting away the const-ness of the data.
This patch changes the code to use an area in the private data for the
board instance to hold the parameters read from EEPROM (after
initializing the parameters from the static board data). It also
changes the type-casts to the read-only data to preserve the const
qualifier.
