i2c: puv3: add CONFIG_PM_SLEEP to suspend function
Add CONFIG_PM_SLEEP to suspend function to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/i2c/busses/i2c-puv3.c:249:12: warning: 'puv3_i2c_suspend' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
