[PATCH] staging: greybus: gbphy: replaced sprintf() with sysfs_emit()

From: Neel Bullywon

Date: Tue Feb 03 2026 - 16:23:23 EST


Replaced sprintf() with sysfs_emit in the protocol_id_show() sysfs
attribute func to prevent any potential buffer overflows

This is to ensure a kernel-wide migration to safer string formatting
functions for sysfs handlers

This was compile-tested only (no VM/hardware used)
