From 4c3032d8a4d6c97bd6e02bcab524ef2428d89561 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sun, 27 Apr 2008 15:38:32 +0200 Subject: ide: add struct ide_io_ports (take 3) * Add struct ide_io_ports and use it instead of `unsigned long io_ports[]` in ide_hwif_t. * Rename io_ports[] in hw_regs_t to io_ports_array[]. * Use un-named union for 'unsigned long io_ports_array[]' and 'struct ide_io_ports io_ports' in hw_regs_t. * Remove IDE_*_OFFSET defines. v2: * scc_pata.c build fix from Stephen Rothwell. v3: * Fix ctl_adrr typo in Sparc-specific part of ns87415.c.
