[PATCH 5/9] scc_pata: store 'hwif' pointer in struct scc_ports

From: Bartlomiej Zolnierkiewicz
Date: Sat Feb 16 2008 - 15:13:51 EST


Replace 'unsigned char hwif_id' by 'ide_hwif_t *hwif' in struct scc_ports.
This allows us to remove ide_hwifs[] usage from scc_remove().

There should be no functional changes caused by this patch.
