Subject: platform/x86/fujitsu-laptop: Replace sprintf() with sysfs_emit()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b35814a3c61f4156aff4d7cf16af097f44c00d79;p=linux.git

platform/x86/fujitsu-laptop: Replace sprintf() with sysfs_emit()

As suggested by Documentation/filesystems/sysfs.rst sysfs_emit() should be
used when formatting the value to be returned to user space.
