+Subject: [PATCH] check_platform_device: Check the length of path
+
+The default length of path is 512, but the strcat() is used without
+check if path is overflowed, otherwise a segfault is observed on
+some aarch64 machines. This patch will use snprintf instead of strcat
+for the buffer length checking.
