From: Bartlomiej Zolnierkiewicz Date: Thu, 17 Apr 2008 22:46:29 +0000 (+0200) Subject: ppc/pmac: remove ppc_ide_md hooks X-Git-Tag: firefly_0821_release~21625^2~20 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5c58666fae58cd69f862beaeb88d293ad00f6e37;p=firefly-linux-kernel-4.4.55.git ppc/pmac: remove ppc_ide_md hooks * Add pmac_ide_init_ports() helper and use it instead of pmac_ide_init_hwif_ports(). * Remove ppc_ide_md hooks - no need for them (IDE pmac host driver takes care of all this setup). * Then remove no longer needed include from arch/powerpc/platforms/powermac/pmac.h.
