From: Joerg Roedel Date: Fri, 9 Aug 2019 16:09:13 +0000 (+0200) Subject: iommu/omap: Fix compilation warnings X-Git-Tag: v5.4-rc1~193^2^2~2 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=73499ad21d595638213f2a5f8b9b58259fa0cae2;p=linux.git iommu/omap: Fix compilation warnings A recent patch introduced a new compiler warning because two functions with non-void return type have no return statement in omap-iommu.h for CONFIG_OMAP_IOMMU=n. Fix this by adding return statements to these functions.
