From 2cb4fade0ef00ebf485db05d6aab4acd8897ecf9 Mon Sep 17 00:00:00 2001 From: Simon Guinot Date: Mon, 21 Nov 2011 19:25:46 +0530 Subject: [PATCH] mvsata: fix ide_preinit for missing disks Consider that ide_preinit() succeed if at least one port is successfully initialized. This allows to iniatialize IDE support on a board with two SATA ports but a single hard disk available.
