Subject: [PATCH] ide: add __ide_default_irq() inline helper
Date: Mon, 7 Jul 2008 22:09:44 +0200 [thread overview]
Message-ID: <200807072209.44933.bzolnier@gmail.com> (raw)
Add __ide_default_irq() inline helper and use it instead of
ide_default_irq() in ide-probe.c and ns87415.c (all host drivers
except IDE PCI ones always setup hwif->irq so it is enough to
check only for I/O bases 0x1f0 and 0x170).
This fixes post-2.6.25 regression since ide_default_irq()
define could shadow ide_default_irq() inline.
