From 2d1d31dda766b146bbd77db5e4e1534f64c92c2b Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 27 Oct 2017 21:21:40 +0200 Subject: mmc: vub300: Use common code in __download_offload_pseudocode() Add a jump target so that a specific string copy operation is stored only once at the end of this function implementation. Replace two calls of the function "strncpy" by goto statements. This issue was detected by using the Coccinelle software.
