[PATCH -next] bus/fsl-mc: Convert sprintf()/snprintf() to sysfs_emit()

[Hongbo Li]

As Documentation/filesystems/sysfs.rst suggested, show()
should only use sysfs_emit() or sysfs_emit_at() when formatting
the value to be returned to user space.

sysfs_emit validates assumptions made by sysfs and is the correct
mechanism to format data for sysfs. So we can do this conversion.
