From 387750c3bf49c22f6189436032145e2131985076 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sun, 27 Apr 2008 15:38:31 +0200 Subject: [PATCH] ide: make ide_unregister() take 'ide_hwif_t *' as an argument (take 2) * Make ide_unregister() take 'ide_hwif_t *hwif' instead of 'unsigned int index' (hwif->index) as an argument and update all users accordingly. While at it: * Remove unnecessary checks for hwif != NULL from ide-pnp.c::idepnp_remove() and delkin_cb.c::delkin_cb_remove(). * Remove needless hwif->chipset assignment from scc_pata.c::scc_remove(). v2: * Fixup ide_unregister() documentation.
