From: Sven Eckelmann Date: Tue, 17 May 2016 15:51:35 +0000 (+0200) Subject: ar71xx: Move OpenMesh image target validation into subfunction X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d1b4a8cfcfb8f3965b79d199993bc847004a7419;p=librecmc%2Flibrecmc.git ar71xx: Move OpenMesh image target validation into subfunction The platform_check_image_openmesh function used break statements to signal that the board name matched the image target. This worked because the sysupgrade binary checked the image inside a loop. The break statement stopped the loop and skipped any additional check. Instead the check should be done without such sideeffects by simply combining the board names and image targets. Only a mismatch should cause a negative result for the caller and skipping of the additional checks.
