From 2a43c9fc878a1d3985207a74f73a1f5aa1342655 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 14 Oct 2019 13:58:01 +0300 Subject: platform/x86: huawei-wmi: Fix a precision vs width printf bug This was supposed to be precision "%.*s" instead of width "%*s". It's possible that this results in printing beyond the end of the string.
