X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=402b362db447c8163b4069537753b1ede3533d18;p=openwrt%2Fstaging%2Fwigyori.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.
