Subject: media: omap: omap-iommu.h: allow building drivers with COMPILE_TEST
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c7f1770f369ae0ec632b3ddc2bd6677b0e485128;p=openwrt%2Fstaging%2Fblogic.git

media: omap: omap-iommu.h: allow building drivers with COMPILE_TEST

Drivers that depend on omap-iommu.h (currently, just omap3isp)
need a stub implementation in order to be built with COMPILE_TEST.
