v2:
 - Add proper commit description
 - No changes in patch

Use kzalloc() instead of kmalloc() + memset() to simplify memory allocation.

Also use sizeof(*board->private_data) instead of repeating the struct name.
This avoids duplication and keeps the code correct if the struct name
changes in the future.
