Subject: ide: add __ide_default_irq() inline helper
X-Git-Tag: firefly_0821_release~19757^2~2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a861beb1401d65e3f095fee074c13645ab06490e;p=firefly-linux-kernel-4.4.55.git

ide: add __ide_default_irq() inline helper

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.
