Subject: [PATCH 2/2] ide: fix ->init_chipset method to return 'int' value
Date: Mon, 19 Jan 2009 19:31:31 +0100 [thread overview]
Message-ID: <200901191931.32044.bzolnier@gmail.com> (raw)
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ide: fix ->init_chipset method to return 'int' value
* Return 0 instead of dev->irq in ->init_chipset implementations.
* Fix ->init_chipset method to return 'int' value instead of
'unsigned int' one.
This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.
