According to Documentation/filesystems/sysfs.rst, the show() callback function of kobject attributes should strictly use sysfs_emit() instead of sprintf() family functions. So, make this change. Issue identified using the coccinelle device_attr_show.cocci script. Signed-off-by: Deepak R Varma <drv@xxxxxxxxx> --- Note: Resending the patch for review and feedback.
