I'm running checkpatch.pl (dated 10/17), and it complains about this line:

Well, that is a bit of a stinker. Maybe it could be reworked a little
to make it easier for humans and checkpatch to understand?
__be32 *crazy_pointer = (void *)firmware + calc_size;
crc = be32_to_cpu(*crazy_pointer);
I admit the code might be convoluted, but it's perfectly valid, and it
eliminates the need for "crazy_pointer". I'm much more inclined to ignore
the checkpatch error than to redesign my code.
Besides, your argument is a bit of a strawman. The real problem is with checkpatch.
(Does this need to worry about get_unaligned() at all?)
Well, I suppose it's technically possible, but only if my data has been corrupted.
