[PATCH v1 1/5] usb: fotg210-hcd: use sysfs_emit() to instead of scnprintf()

From: Andy Shevchenko
Date: Fri Jan 20 2023 - 10:44:12 EST


Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
