Subject: genirq: provide old request_irq() for CONFIG_GENERIC_HARDIRQ=n
X-Git-Tag: v2.6.30-rc1~3^2~2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3a38148f0488069cadb75c4a6909954072d648bf;p=karo-tx-linux.git

genirq: provide old request_irq() for CONFIG_GENERIC_HARDIRQ=n

Impact: Undo compile breakage for archs with CONFIG_GENERIC_HARDIRQ=n

The threaded interrupt handler patches changed request_irq from extern
to inline. Architectures which do not use the generic irq code still
have request_irq() as a global function and therefor fail to compile.

Keep the extern declaration for CONFIG_GENERIC_HARDIRQ=n
