[PATCH][TRIVIAL]drivers: Fix a class of compiler warnings

[Wang YanQing]

Fix the warnings look like below:
/linux/drivers/dma/timb_dma.c:801: warning: 'td_remove' defined but not used

I get the warning above when I compile 3.8.6 kernel,
then I fix it and others' same issue in kernel with
the help of perl, then I review and check the changes
one by one.
