you have to start from the beginning again. :(
I have faced such similar situation also, but starting for the beginnig
is the only way.

but it looks like they were introduced in your patch.

the original code was having three u32, i think when you moved one more
u32 from the following line you forgot to remove the space after that.

i dont think checkpatch can work like that way.
identification was easy. i saw checkpatch giving error and noticed you
have modified the code. So i checked the original code if trailing
whitespace was there or not.
