X-Git-Tag: firefly_0821_release~176^2~3754^2~13
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d13f19f2ca7fb6b545915e96ffe19bb405b72037;p=firefly-linux-kernel-4.4.55.git

[media] omap3isp: queue: Inline the ispmmu_v(un)map functions

The ispmmu_vmap() and ispmmu_vunmap() functions are just wrappers around
omap_iommu_vmap() and omap_iommu_vunmap(). Inline them.
