[PATCH v2 6/6] staging: dgnc: changes arguments in sizeof

[Lidza Louina]

The arguments that are passed into sizeof were
generic. This patch changes this by putting
the actual item that we need a size of instead.

For example:
-   kzalloc(sizeof(struct dgnc_board), GFP_KERNEL);
+   kzalloc(sizeof(brd), GFP_KERNEL);
