This patch fixes sdio_io sparse errors.
This fix changes signature of API functions,
changing
unsigned char -> u8
unsigned short -> u16
unsigned long -> u32 - this was probably a bug in 64 bit platforms

why are we not using the new get_unaligned_le* and put_unaligned_le*
functions for the tmpbuf access?

It resides inside sido_func structure there is no reason it will be
unaligned.

A nice addition, but I'm afraid that field is not present on all cards
(it was added in version 1.1). Could you make sure you have the proper
guards and a fallback?

I'm not entirely comfortable with this as the point was to use the same
types as the "real" read*/write*. But as i386 and x86_64 use different
types, I don't see much choice.
I've applied the patch.
