From 77806ad75a01458eb7ee4fcd0178b7f1600830fd Mon Sep 17 00:00:00 2001 From: Andrea Dalla Costa Date: Sat, 11 Jan 2020 22:41:31 +0100 Subject: [PATCH] firmware-utils: fix possible memory leak and resource leak Add missing calls to `free` for variable `buffer`. This could lead to a memory leak. Add missing call to `close` for file pointer `fdin`. This could lead to a resource leak.
