Subject: [PATCH v2] HID: roccat-*: Convert snprintf() to sysfs_emit()
Date: Mon, 10 Oct 2022 11:57:15 +0100 [thread overview]
Message-ID: <Y0P6i8LTdgVX+0O4@octinomon> (raw)
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()
