May be size_t should be used for fw_length? Corresponding argument of
the snprintf()
has size_t type, sizeof(drvinfo.fw_version) is used as value of the
parameter.
Also the prototype does not provide a way to communicate that fw_length
is insufficient
to store firmware version. I'd suggest snprintf()-like return value. It
is pretty easy for PMD
to provide and convenient for the API function caller to handle.
