Hi kbuild_test_robot,
This patch that it can be applied to git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next
For the compile error, you need to apply the patch "https://patchwork.kernel.org/patch/10645289/"; first,

Thanks for your explanation.  the robot is not smart enough to handle 
this situation,
git format-patch uses '--base' option torecord base tree info. you could 
add the option
to help the robot find the right base tree.

Best Regards,
Rong Chen
