This patch fixes up some issues with patch 03/15 in the wl128x support
series:
* Fix endianess issues;
* Simplify sdio-specific block_size handling;
* Minor changes in comments
This has been compile-tested only. I will test this changes after I
go through the whole series and, if everything is still ok, I'll merge
this patch into 03/15.
