Subject: [Buildroot] [PATCH 1/1] package/linux-firmware: fix build failure
 when no firmware item selected
Message-ID: <539abc1b8ea48daa694b45242cab63d0@umbiko.net>
List-Id: <buildroot.busybox.net>

The latest change in Linux firmware handling breaks the build if no 
specific firmware item is selected below BR2_PACKAGE_LINUX_FIRMWARE.

The firmware archive is only created if at least one firmware 
sub-category is selected; the installation step wants to unpack the 
archive unconditionally.

Use the same condition to control install command definition as in the 
build step.
