Hi Wolfram,

I began testing the card you sent today. I'm getting a firmware load
error like you mentioned.

I checked out code from when you originally merged into staging,
however I built the module in a 4.9 kernel.

To help me track down the issue could you please tell me what testing
you managed to do successfully in the past, and if you can,
approximately the date you were doing the tests or the git commit of
the code you tested.

Thanks. Oh, also could you please indicate your level of interest my
continued efforts. I don't want to send you copious emails if you
would rather me not.

For anyone on the lists reading this, the hardware is

Spectec SDW-823 microSD (SDIO) Wi-Fi card

The error code is -EILSEQ (Illegal byte sequence). It is returned by
sdio_memcpy_fromio(). I do not know what it signifies?

thanks,
Tobin.

Nice. Firstly, that means the card is alive and survived the mailing.

I think building a vanilla 4.9 kernel is a good choice. I did test the
card with v4.9. I am quite (but not perfectly) sure, I also tested it
with v4.10.

The tests I did are described here:

http://elinux.org/Tests:SDIO-KS7010

The branch I used is mentioned there

https://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git/log/?h=renesas/topic/gen3-sdio

but it is based on a branch called renesas-drivers (which is some kind
of stripped down linux-next targeted for Renesas R-Car hardware), so I'd
think v4.9 is the better choice.

The tests were all done End of May 2016.

I'm definately interested. I might not be able to review patches, but
for high level questions like this, please CC me. However, give me a few
days for a response.

I use it rarely, but in this case, I'd think bisecting from v4.9 onwards
is a good choice to tackle this down (given that v4.9 works; otherwise
we'll have to check the MMC layer).

Thanks and all the best,
