I think I figured it out. I am applying the patches on top of the next 
branch from git://git.linaro.org/people/ulf.hansson/mmc.git. However, I 
am still not getting a compiler warning. Perhaps it has to do with the 
gcc version. I'm not exactly sure how to fix it since it is really not 
used uninitialized. Just set it to 0 in the variable declaration?
