ide-iops.c exports a few functions that either have no users or have no
users AND shouldn't be used by drivers; the patch below unexports them.

-EXPORT_SYMBOL(SELECT_INTERRUPT);
-EXPORT_SYMBOL(SELECT_MASK);
-EXPORT_SYMBOL(QUIRK_LIST);
-EXPORT_SYMBOL(ata_vlb_sync);

only used in the core ide code

-EXPORT_SYMBOL(ata_input_data);
-EXPORT_SYMBOL(ata_output_data);

drivers should (and do) use the hwif-> function pointer variant of these,
these functions are internal and used for setting the default hwif->
function pointers only. No need to export, in fact exporting is only asking
for accidents
