[PATCH 2/3] tty: cyclades: cyz_interrupt is only used for PCI
From: Arnd Bergmann
Date: Mon Jan 25 2016 - 16:56:10 EST
When CONFIG_PCI is not set, enabling CONFIG_CYZ_INTR has no
practical effect other than generating a warning about an
unused function:
drivers/tty/cyclades.c:1184:20: warning: 'cyz_interrupt' defined but not used [-Wunused-function]
static irqreturn_t cyz_interrupt(int irq, void *dev_id)
This adds a dependency to avoid that warning.
