Since commit 868941b14441 ("fs: remove no_llseek"), no_llseek() is
simply defined to be NULL, and a NULL llseek means seeking is
unsupported.
So for statically defined file_operations, such as all these, there's no
need or benefit to set llseek = no_llseek.

The overflow/underflow conditions in pata_macio_qc_prep() should never
