Subject: [PATCH 2/3] tty: cyclades: cyz_interrupt is only used for PCI
Date: Mon, 25 Jan 2016 22:54:57 +0100 [thread overview]
Message-ID: <1453758918-3577213-2-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1453758918-3577213-1-git-send-email-arnd@arndb.de>
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.
