Subject: [PATCH] staging: fluke_gpib: use kzalloc instead of kmalloc + memset

Thanks, the commit message now includes a proper description.
The patch itself has not changed.
I also realized that the previous subject line might have been incorrect.
The correct subject should be:
staging: gpib: eastwood: use kzalloc instead of kmalloc + memset
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.
