[PATCH] staging: greybus: gbphy: use sysfs_emit() instead of sprintf()

[Mohit Mishra <mishraloopmohit@gmail.com>]

protocol_id_show() uses sprintf() to format sysfs output into the page
buffer. Convert it to sysfs_emit(), which is the preferred helper for
sysfs show() callbacks as it enforces page boundary checks.

Similar conversions have already been made elsewhere in this subsystem
(e.g. loopback.c, arche-platform.c).
