Subject: [PATCH 24/29] usb: fotg210-hcd: use sysfs_emit() to instead of
|
||
|
|
scnprintf()
|
||
|
|
|
||
|
|
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.
