This patchset proposes some internal and externally-visible changes to the
rawdev API, the ABI change of which were previously announced.
The changes are in two main areas:
* For any APIs which take a void * parameter for driver-specific structs,
add an additional parameter to provide the struct length. This allows
some runtime type-checking, as well as possible ABI-compatibility support
in the future as structure change generally involve a change in the size
of the structure.
* Ensure all APIs which can return error values have int type, rather than
void. Since functions like info_get and queue_default_get can now do some
typechecking, they need to be modified to allow them to return error
codes on failure.
V2:
- add additional patch to make start/stop functions optional
- remove deprecation notice once changes applied
