I have been getting this message since I started to use 3.0 series'
kernels. I found this (https://lkml.org/lkml/2011/5/4/516) topic
related to this warning.
Best regards,
Numan.

Hopefully I have added some relevant Cc's. The sdhci driver attempting
to abuse sysfs and sysfs is refusing to put up with it.
Can someone who understands the sdhci driver take a look at this?
