4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 05ead49691d245f67bdd1b30cab5d9af522ac884 upstream.
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.
