The others are good, but this one is not right.

We don't use far pointers in linux.  When you're casting something
there is no space between the cat operation and the variable.  The
reason is that casting is a high precedence operation.

More readable:  (char *)p + 1;
Less readable:  (char *) p + 1;

In the first line it's obvious that we cast first and then add 1.

So this should be:
	(hcf_8 *)fw_image_1_data,
