genirq: provide irq_to_desc() to non-genirq architectures too
Impact: build fix on non-genirq architectures
Sam Ravnborg reported this build failure on sparc32 allmodconfig,
the GPIO drivers assume the presence of irq_to_desc():
drivers/gpio/gpiolib.c: In function `gpiolib_dbg_show':
drivers/gpio/gpiolib.c:1146: error: implicit declaration of function 'irq_to_desc'
Add it in the !genirq case too.
