Subject: Re: [PATCH] Fix NULL pointer dereference in sd_revalidate_disk

I have tested this patch, and it fixes the problem where when I ejected the SD
card it would oops and crash and burn my kernel, as reported here :

https://lkml.org/lkml/2012/2/7/462

and here:

https://bugs.gentoo.org/show_bug.cgi?id=402433

I tested it with the 3.3-rc5 sources, found here:

Thanks,

Tested-by:Naveen Goswamy
