Add CONFIG_PM_SLEEP to suspend/resume functions 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-mpc.c:724:12: warning: 'mpc_i2c_suspend' defined but not used [-Wunused-function] drivers/i2c/busses/i2c-mpc.c:734:12: warning: 'mpc_i2c_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@samsung.com> --- drivers/i2c/busses/i2c-mpc.c | 6 ++---- 1 files changed, 2 insertions(+), 4 deletions(-)
