Subject: [PATCH] i2c-designware: define i2c_dw_pci_runtime_idle only with runtime pm
Date: Fri, 27 Sep 2013 00:24:03 +0200 [thread overview]
Message-ID: <1380234243-23787-1-git-send-email-vincent.stehle@laposte.net> (raw)
Make sure i2c_dw_pci_runtime_idle() is defined only when actually used, when
CONFIG_PM_RUNTIME is defined.
This fixes the following compilation warning:
drivers/i2c/busses/i2c-designware-pcidrv.c:188:12: warning: ‘i2c_dw_pci_runtime_idle’ defined but not used [-Wunused-function]
