From 14f66d65a33f622b8138ab0fcd1e18060a2355c2 Mon Sep 17 00:00:00 2001 From: Tang Yuantian Date: Wed, 6 May 2015 11:21:33 +0800 Subject: [PATCH] fsl/sata: Replace sprintf() with snprintf() Function 'sprintf' does not check buffer boundaries but outputs to the buffer of fixed size which could potentially cause buffer overflow. Use a safer function to replace it.
