These variables were only assigned some value and were never used.

I have removed the variables in the functions gru_dump_tfm() and
gru_dump_tgh() but it appeared that the intended logic might have been
something like:
bytes = GRU_NUM_TFM * GRU_CACHE_LINE_BYTES;
if (bytes > ubufend - ubuf)
return -EFBIG;
But since I was not sure so removing the variable was the safe choice as
it is not changing the logic.
