Subject: firmware-utils/dgfirmare: fix possible resource leak
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d3677bbf7e67396a005b2e9d1bf2262d49c5294a;p=project%2Ffirmware-utils.git

firmware-utils/dgfirmare: fix possible resource leak

Add missing calls to `fclose` in functions `write_img`, `write_rootfs`
and `write_kernel`.
The not-closed files could lead to resource leaks.
