Can you go into a bit more detail here?

I should indeed use get_unaligned for accessing the 32-bit
patch_offset values as they might not be 4-byte aligned.
The others should be fine though.

Or are you suggesting some helper that I can use to clean up the code
in this area? If so, could you be a little more specific?

There is already /lib/firmware/rtl_nic used by r8169 driver, I was
going for consistency with that. There is also /lib/firmware/rtlwifi.
Does that influence your preference?

I'll address all other comments in the next patch.

Thanks
Daniel
