Subject: platform/mellanox: mlxreg-hotplug: use sysfs_emit() instead of sprintf()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fcf1b6f8d8248b4c79e5f7c506010d389f1e4f16;p=users%2Fwilly%2Flinux.git

platform/mellanox: mlxreg-hotplug: use sysfs_emit() instead of sprintf()

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