irda: fix !PNP support in drivers/net/irda/nsc-ircc.c
x86.git testing found the following build failure in latest -git: drivers/built-in.o: In function `nsc_ircc_pnp_probe': nsc-ircc.c:(.text+0xdf1b6): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf1d4): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf1ee): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf237): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf24c): undefined reference to `pnp_get_resource' drivers/built-in.o:nsc-ircc.c:(.text+0xdf266): more undefined references to `pnp_get_resource' follow make: *** [.tmp_vmlinux1] Error 1 triggered via this config: http://redhat.com/~mingo/misc/config-Sat_May__3_20_53_13_CEST_2008.bad while generally most users will have PNP enabled, drivers can support non-PNP build mode too - and most drivers implement it. That is typically done by providing a dummy pnp_driver structure that will not probe anything. The fallback routines in the driver will handle this dumber mode of operation too. This patch implements that. I have not tested whether this actually works on real hardware so take care. It does resolve the build bug. [ Another solution that is used by a few drivers is to exclude the driver in the Kconfig if PNP is disabled, via "depends on PNP", but this would limit the availability of the driver needlessly. ] Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David S.
