Subject[PATCH] media: i2c: imx290: make suspend/resume functions __maybe_unused
Date
GCC reports that these 2 functions are defined but not used, so mark
them as __maybe_unused to pacify the build.

drivers/media/i2c/imx290.c:1090:12: warning: 'imx290_runtime_suspend' defined but not used [-Wunused-function]
1090 | static int imx290_runtime_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~
drivers/media/i2c/imx290.c:1082:12: warning: 'imx290_runtime_resume' defined but not used [-Wunused-function]
1082 | static int imx290_runtime_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~
