In your git you have

http://git.linaro.org/gitweb?p=people/riczhao/linux-2.6.git;a=commitdiff;h=4bd46e7f8ade05984ee89222bc0523b656d017d2

-       if (sdmac->event_id0) {
-               if (sdmac->event_id0 > 32)
-                       return -EINVAL;
+       if (sdmac->event_id0)
                 sdma_event_enable(sdmac, sdmac->event_id0);

I your git version outdated and replaced by this patch?
