From: Bartlomiej Zolnierkiewicz Date: Thu, 17 Apr 2008 22:46:29 +0000 (+0200) Subject: ppc/mpc8xx: remove ppc_ide_md hooks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2661b13a21f609b279b4048978f8625d518df6e1;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git ppc/mpc8xx: remove ppc_ide_md hooks * Initialize IDE ports in mpc8xx_ide_probe(). * Remove m8xx_ide_init() and ppc_ide_md hooks - no need for them (IDE mpc8xx host driver takes care of all this setup). * Remove needless 'if (irq)' and 'if (data_port >= MAX_HWIFS)' checks from m8xx_ide_init_hwif_ports(). * Remove 'ctrl_port' and 'irq' arguments from m8xx_ide_init_hwif_ports(). * Rename m8xx_ide_init_hwif_ports() to m8xx_ide_init_ports(). * Add __init tag to m8xx_ide_init_ports(). This patch fixes hwif->irq always being overriden to 0 (== auto-probe, is this even working on PPC?) because of ide_init_default_irq() call in ide.c. There should be no other functional changes.
