media: imon: Convert sprintf/snprintf to sysfs_emit
Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). sprintf() will be converted as weel if they have. Generally, this patch is generated by make coccicheck M=<path/to/file> MODE=patch \ COCCI=scripts/coccinelle/api/device_attr_show.cocci No functional change intended Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
