[PATCH 3/3] HID: roccat: Convert snprintf() to sysfs_emit()

[PATCH 3/3] HID: roccat: Convert snprintf() to sysfs_emit()

[Jules Irenge]

Coccinnelle reports a warning
Warning: Use scnprintf or sprintf

Following the advice on kernel documentation
https://www.kernel.org/doc/html/latest/filesystems/sysfs.html

For show(device *...) functions we should only use sysfs_emit() or sysfs_emit_at()
especially when formatting the value to be returned to user space.

Convert snprintf() to sysfs_emit()
