The change looks good, but the same driver also uses the BKL in the
default_llseek function. It would be nice to get rid of that in the
same patch, e.g. by adding a ".llseek = generic_file_llseek," line
in the file_operations, or making it call nonseekable_open() if the
driver does not require seek to do anything.
