Subject[PATCH 2/7] habanalabs: align ioctl uapi structures to 64-bit
Date
From: Dan Rapaport <drapaport@habana.ai>

The compiler is padding the members of the struct to be aligned to
64-bit. The content of the padded bytes is and not zeroed explicitly,
hence might copy undefined data. We add a padding member to the struct
to get a zeroed 64-bit align struct.
