From: Bartlomiej Zolnierkiewicz Subject: [PATCH] ide: remove hwif->intrproc Given that: * hpt366.c::hpt3xx_intrproc() is the only user of hwif->intrproc * hpt366.c::hpt3xx_quirkproc() sets drive->quirk_list to 1 for quirky drives which is a value unique to hpt366 host driver we can remove hwif->intproc and just check for drive->quirk_list == 1 in ide_do_request().
